Detailed Description
Introduction
The AOZ1360 is a 35mΩ P-channel high-side load switch with adjustable soft-start slew-rate control,
programmable current limit and thermal shutdown. It operates with an input voltage range from 5.5V to 28V and
can handle a continuous current of 2A.
Enable
The Enable pin is the ON/OFF control for the output switch. It’s an active-high input. The EN pin is active after
V
UVLO of 2.0V. The EN pin must be driven to a logic high or logic low state to guarantee operation. While
disabled, the AOZ1360 only draws about 1uA supply current. The EN is a high impedance input with an ESD
protection diode to ground and should not be forced below ground. This input level is compatible with most
microcontroller outputs and other logic families.
Under-Voltage Lockout (UVLO)
The under-voltage lockout (UVLO) circuit of AOZ1300 monitors the input voltage and prevents the output
MOSFET from turning on until VIN exceeds 4.9V.
Adjustable Soft-Start Slew-Rate Control
When the EN pin is asserted high, the slew rate control circuitry applies voltage on the gate of the PMOS switch
in a manner such that the output voltage and current is ramped up linearly until it reaches the steady-state load
current level. The slew rate can be adjusted by an external capacitor connected to the SS pin to ground. The
slew rate rise time, Ton, can be set using the following equation:
