Pin Description
Pin # Name Function
1 GND Ground
2 IN Supply Input: Input to the power switch and the supply voltage for the IC.
3 ONA ON / OFF control input of power switch A. Active LOW
4 ONB ON / OFF control input of power switch B. Active LOW
5FLAGB(B)
Fault Output B, Active LO, open drain output which indicates an over supply, UVLO
and thermal shutdown.
6 OUTB Switch Output: Output of the power switch B
7 OUTA Switch Output: Output of the power switch A
8FLAGB(A)
Fault Output A, Active LO, open drain output which indicates an over supply, UVLO
and thermal shutdown.
9(MLP) Thermal Pad
IC Substrate, which can be connected to GND for better thermal performance. Do not
connect to other pins.
