DESCRIPTION  
The TPS201xA family of power distribution switches is intended for applications where heavy capacitive loads  
and short circuits are likely to be encountered. These devices are 50-mN-channel MOSFET high-side power  
switches. The switch is controlled by a logic enable compatible with 5-V logic and 3-V logic. Gate drive is  
provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize  
current surges during switching. The charge pump requires no external components and allows operation from  
supplies as low as 2.7 V.  
When the output load exceeds the current-limit threshold or a short is present, the TPS201xA limits the output  
current to a safe level by switching into a constant-current mode. When continuous heavy overloads and short  
circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal  
protection circuit shuts off the switch to prevent damage. Recovery from a thermal shutdown is automatic once  
the device has cooled sufficiently. Internal circuitry ensures the switch remains off until valid input voltage is  
present.

DETAILED DESCRIPTION  
POWER SWITCH  
The power switch is an N-channel MOSFET with a maximum on-state resistance of 50 m(VI(IN) = 5V).  
Configured as a high-side switch, the power switch prevents current flow from OUT to IN and IN to OUT when  
disabled.  
CHARGE PUMP  
An internal charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate  
of the MOSFET above the source. The charge pump operates from input voltages as low as 2.7 V and requires  
very little supply current.  
DRIVER  
The driver controls the gate voltage of the power switch. To limit large current surges and reduce the associated  
electromagnetic interference (EMI) produced, the driver incorporates circuitry that controls the rise times and fall  
times of the output voltage. The rise and fall times are typically in the 2-ms to 9-ms range.  
ENABLE (EN)  
The logic enable disables the power switch, the bias for the charge pump, driver, and other circuitry to reduce the  
supply current to less than 10 μA when a logic high is present on EN . A logic zero input on EN restores bias to  
the drive and control circuits and turns the power on. The enable input is compatible with both TTL and CMOS  
logic levels.  
CURRENT SENSE  
A sense FET monitors the current supplied to the load. The sense FET measures current more efficiently than  
conventional resistance methods. When an overload or short circuit is encountered, the current-sense circuitry  
sends a control signal to the driver. The driver, in turn, reduces the gate voltage and drives the power FET into  
its saturation region, which switches the output into a constant current mode and holds the current constant while  
varying the voltage on the load.  
THERMAL SENSE  
An internal thermal-sense circuit shuts off the power switch when the junction temperature rises to approximately  
140°C. Hysteresis is built into the thermal sense circuit. After the device has cooled approximately 20°C, the  
switch turns back on. The switch continues to cycle off and on until the fault is removed.  
UNDERVOLTAGE LOCKOUT  
A voltage sense circuit monitors the input voltage. When the input voltage is below approximately 2 V, a control  
signal turns off the power switch.

APPLICATION INFORMATION  
Figure 35. Typical Application  
POWER-SUPPLY CONSIDERATIONS  
A 0.01-μF to 0.1-μF ceramic bypass capacitor between IN and GND, close to the device, is recommended.  
Placing a high-value electrolytic capacitor on the output and input pins is recommended when the output load is  
heavy. This precaution reduces power supply transients that may cause ringing on the input. Additionally,  
bypassing the output with a 0.01-μF to 0.1-μF ceramic capacitor improves the immunity of the device to  
short-circuit transients.  
OVERCURRENT  
A sense FET checks for overcurrent conditions. Unlike current-sense resistors, sense FETs do not increase the  
series resistance of the current path. When an overcurrent condition is detected, the device maintains a constant  
output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault is present  
long enough to activate thermal limiting.  
Three possible overload conditions can occur. In the first condition, the output has been shorted before the  
device is enabled or before VI(IN) has been applied (see Figure 6). The TPS201xA senses the short and  
immediately switches into a constant-current output.  
In the second condition, the excessive load occurs while the device is enabled. At the instant the excessive load  
occurs, very high currents may flow for a short time before the current-limit circuit can react (see  
Figure 12Figure 19). After the current-limit circuit has tripped (reached the overcurrent trip threshold) the device  
switches into constant-current mode.  
In the third condition, the load has been gradually increased beyond the recommended operating current. The  
current is permitted to rise until the current-limit threshold is reached or until the thermal limit of the device is  
exceeded (see Figures Figure 77–Figure 10). The TPS201xA is capable of delivering current up to the  
current-limit threshold without damaging the device. Once the threshold has been reached, the device switches  
into its constant-current mode.  
POWER DISSIPATION AND JUNCTION TEMPERATURE  
The low on-resistance on the n-channel MOSFET allows small surface-mount packages, such as SOIC, to pass  
large currents. The thermal resistance of these packages are high compared to those of power packages; it is  
good design practice to check power dissipation and junction temperature. The first step is to find rDS(on) at the  
input voltage and operating temperature. As an initial estimate, use the highest operating ambient temperature of  
interest and read rDS(on) from SLVS1892074Figure 30Figure 33 . Next, calculate the power dissipation using:

Where:  
TA = Ambient Temperature °C  
θJA = Thermal resistance SOIC = 172°C/W  
R
Compare the calculated junction temperature with the initial estimate. If they do not agree within a few degrees,  
repeat the calculation, using the calculated value as the new estimate. Two or three iterations are generally  
sufficient to get an acceptable answer.  
THERMAL PROTECTION  
Thermal protection prevents damage to the IC when heavy-overload or short-circuit faults are present for  
extended periods of time. The faults force the TPS201xA into constant current mode, which causes the voltage  
across the high-side switch to increase; under short-circuit conditions, the voltage across the switch is equal to  
the input voltage. The increased dissipation causes the junction temperature to rise to high levels. The protection  
circuit senses the junction temperature of the switch and shuts it off. Hysteresis is built into the thermal sense  
circuit, and after the device has cooled approximately 20 degrees, the switch turns back on. The switch continues  
to cycle in this manner until the load fault or input power is removed.  
UNDERVOLTAGE LOCKOUT (UVLO)  
An undervoltage lockout ensures that the power switch is in the off state at power up. Whenever the input  
voltage falls below approximately 2 V, the power switch will be quickly turned off. This facilitates the design of  
hot-insertion systems where it is not possible to turn off the power switch before input power is removed. The  
UVLO will also keep the switch from being turned on until the power supply has reached at least 2 V, even if the  
switch is enabled. Upon reinsertion, the power switch will be turned on, with a controlled rise time to reduce EMI  
and voltage overshoots.  
GENERIC HOT-PLUG APPLICATIONS (see Figure 36)  
In many applications it may be necessary to remove modules or p-c boards while the main unit is still operating.  
These are considered hot-plug applications. Such implementations require the control of current surges seen by  
the main power supply and the card being inserted. The most effective way to control these surges is to limit and  
slowly ramp the current and voltage being applied to the card, similar to the way in which a power supply  
normally turns on. Because of the controlled rise times and fall times of the TPS201xA series, these devices can  
be used to provide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of  
the TPS201xA also ensures the switch will be off after the card has been removed, and the switch will be off  
during the next insertion. The UVLO feature guarantees a soft start with a controlled rise time for every insertion  
of the card or module.  
Figure 36. Typical Hot-Plug Implementation  
By placing the TPS201xA between the VCC input and the rest of the circuitry, the input power will reach this  
device first after insertion. The typical rise time of the switch is approximately 9 ms, providing a slow voltage  
ramp at the output of the device. This implementation controls system surge currents and provides a  
hot-plugging mechanism for any device.
