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.

DETAILED DESCRIPTION
The MP62040-1/MP62041-1 Power Distribution
Switch is designed for high-side load switch. The
switch operates from 1.7V to 5.5V nominal input
voltage and can handle up to 2A continuous load.
Output Discharge
The part includes a discharge function that
provides a resistive discharge path for the
external output capacitor. This function allows the
device to quickly discharge the output voltage
when it’s disabled.
Enable
The logic pin disables the switch to reduce overall
supply current .Once the EN pin reaches logic
enable threshold, the MP62040-1/MP62041-1 is
enabled and the supply current is very small, only
2µA.
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.
