APL3534
The APL3534/A/B is a power-distribution switch with cur-
rent- limiting function and output OVP protections that can
deliver current up to 1A. The device incorporates a 110mΩ
N-channel MOSFET power switch.
The device integrates some protection features, includ-
ing current-limit protection, output over-voltage protection,
over-temperature protection and UVLO. The current-limit
protection can protect down-stream devices from cata-
strophic failure by limiting the output current at current-
limit threshold during over-load or short-circuit events.
The output over-voltage protection can prevent current
flowing from VOUT to VIN when an abnormally high volt-
age exists in VOUT. The over-temperature protection func-
tion shuts down the N-channel MOSFET power switch
when the junction temperature rises beyond 140oC and
will automatically turns on the power switch when the
temperature drops by 20oC. The UVLO function keeps
the power switch in off state until there is a valid input
voltage present.
The device is available in lead free SOT-23-3 and
SOT-23-5 packages.

Output Voltage Pin. The output voltage follows the input voltage. When EN is low or
VIN is UVLO, the output voltage is discharged by an internal resistor.
Power Supply Input Connect this pin to external DC supply.
Pulling the ENB above 2V or EN below 0.8V will disable the device, and pulling ENB
pin below 0.8V or EN above 2V will enable the device.
The EN and ENB pins cannot be left floating.
Not Connected Internally.
