Gereral Description
The APL3538 is an ultra-low On-resistance, dual power-
distribution switch with external soft start control. It inte-
grates two N-channel MOSFETs that can deliver 6A con-
tinuous load current each. The APL3538 can be enabled
by other power systems. Pulling and holding the voltage
of EN pin (APL3538A) below 0.4V shuts off the output.
Pulling and holding the voltage of ENB pin (APL3538B)
below 0.4V enable the output. The device integrates some
protection features, including Over-Current Protection
(OCP) and Over-Temperature Protection (OTP). The OCP
can protect the device against current over-loads or short-
circuit events. The OTP function shuts down the N-chan-
nel MOSFET power switch when the junction tempera-
ture rises beyond 150°C and will automatically turns on
the power switch when the temperature drops by 30°C.
The device is available in lead free TQFN2x2-14 package.
