1A Continuous Current
Accurate Current Limit
The
MP6211/MP6212
single-channel
Power
Distribution Switch features internal current limiting
to prevent damage to host devices due to faulty load
conditions. The MP6211/MP6212 Analog switch has
90mΩ on-resistance and operates from 2.7V to 5.5V
input. It is available with guaranteed current limits,
making it ideal for load switching applications. The
MP6211/MP6212 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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) Measured on JESD51-7 4-layer PCB.

MP6211/MP6212 –CURRENT-LIMITED POWER DISTRIBUTION SWITCHES
DETAILED DESCRIPTION
Over Current
Thermal Protection
When the load exceeds trip current (minimum
threshold current triggering constant-current
mode) or a short is present, MP6211/MP6212
switches into to a constant-current mode (current
limit value). MP6211/MP6212 will be shutdown
only if the overcurrent condition stays long
enough to trigger 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.
Trigger overcurrent protection for different
overload conditions occurring in applications:
Under-voltage Lockout (UVLO)
This circuit is used to monitor the input voltage to
ensure that the MP6211/6212 is operating
correctly. This UVLO circuit also ensures that
there is no operation until the input voltage
reaches the minimum spec.
1) The output has been shorted or overloaded
before the device is enabled or input applied.
MP MP6211/MP6212 detects the short or
overload and immediately switches into a
constant-current mode.
Enable
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-
current mode. However, high current may
flow for a short period of time before the
current-limit circuit can react.
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.
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 MP6211/
MP6212 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.
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.

APPLICATION INFORMATION
Power-Supply Considerations
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.
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.
