The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP62130/MP62131 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62130/MP62131
Analog switch features 90mΩ on-resistance
and operates from 2.7V to 5.5V input. It is
available with a guaranteed current limit,
making it ideal for load switching applications.
The MP62130/MP62131 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.

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.
The MP62130/MP62131 is available in MSOP8
and SOIC8 packages.

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-toambient 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.

Over Current
When the load exceeds trip current (minimum
threshold current triggering constant-current
mode) or a short is present, MP62130/MP62131
switches into to a constant-current mode (current
limit value). MP62130/MP62131 will be shutdown
only if the overcurrent condition stays long
enough to trigger thermal protection.
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
temperature is internally monitored until the
thermal limit is reached. Once this temperature 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:
1) The output has been shorted or overloaded
before the device is enabled or input applied.
MP62130/MP62131 detects the short or
overload and immediately switches into a
constant-current mode.
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.
Output Discharge
The part involves a discharge function that
provides a resistive discharge path for the
external output capacitor. The function will be
active when the part is disabled (Input voltage is
under UVLO or enable is deasserted) and it will
be done in a very limited time.
T
R
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 constantcurrent mode. However, high current may
flow for a short period of time before the
current-limit circuit can react.
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
MP62130/MP62131 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.
Under-Voltage Lockout (UVLO)
This circuit is used to monitor the input voltage to
ensure that the MP62130/MP62131 is operating
correctly. This UVLO circuit also ensures that
there is no operation until the input voltage
reaches the minimum spec.
N
O
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 temperature or voltage lockout.

transients that may cause ringing on the input.
Optionally, bypassing the output with a 0.01µF to
0.1µF ceramic capacitor improves the immunity
