The MP6233 Power Distribution Switch features
internal current limiting to prevent damage to
host devices due to faulty load conditions. The
MP6233 analog switch includes an 85mΩ
power MOSFET switch. It is available with
guaranteed current limits, making it ideal for
load switching applications. The MP6233 has
built-in protection for both over current and
increased thermal stress. For over current, the
device will limit the current by changing to a
constant current mode.
APPLICATIONS
As the temperature increases as a result of
short circuit, the device will shut off. The device
will recover once the device temperature
reduces to approx 120°C.

flow for a short period of time before the
current-limit circuit can react.
Over Current
When the load exceeds trip current (minimum
threshold current triggering constant-current
mode) or a short is present, MP6233 switches
into to a constant-current mode (current limit
value). MP6233 will be shutdown only if the
overcurrent condition stays long enough to
trigger thermal protection.
3) Output current has been gradually increased
beyond the recommended operating current.
The load current rises until the trip current
threshold is reached or until the thermal limit
of the device is exceeded. The MP6233 is
capable of delivering current up to the trip
current threshold without damaging the
device. Once the trip threshold has been
reached, the device switches into its
constant-current mode.
Trigger overcurrent protection for different
overload conditions occurring in applications:
1) The output has been shorted or overloaded
before the device is enabled or input applied.
MP6233 detects the short or overload and
immediately switches into a constant-current
mode.
2) A short or an overload occurs after the device
is enabled. After the current-limit circuit has
been tripped (reached the trip current
threshold), the device switches into constant-
Flag Response
The FLAG pin is an open drain configuration.
This FAULT will report a fail mode after an 8ms
deglitch timeout. This is used to ensure that no
false fault signals are reported. This internal
deglitch circuit eliminates the need for extend
components. The FLAG pin is not deglitched
during an over temp. or a voltage lockout.

Thermal Protection
The purpose of thermal protection is to prevent
damage in the IC by allowing exceptive current to
flow and heating the junction. The die temp. is
internally monitored until the thermal limit is
reached. Once this temp. is reached, the switch
will turn off and allow the chip to cool. The switch
has a built-in hysteresis.
operation until the input voltage reaches the
minimum spec.
Enable
The logic pin disables the chip to reduce the
supply current. The device will operate once the
enable signal reaches the appropriate level. The
input is compatible with both COMS and TTL.
Under-voltage Lockout (UVLO)
This circuit is used to monitor the input voltage to
ensure that the MP6233 is operating correctly.
This UVLO circuit also ensures that there is no

APPLICATION INFORMATION
Power-Supply Considerations
Over 10μF capacitor between IN and GND is
recommended.
This precaution reduces power-supply transients
that may cause ringing on the input and improves
the immunity of the device to short-circuit
transients.
In order to achieve smaller output load transient
ripple, placing a high-value electrolytic capacitor
on the output pin(s) is recommended when the
load is heavy.
