PIN FUNCTION DESCRIPTIONS

Pin

Mnemonic

Function

1, 4, 5, 12, 13, 16

IN

Input to P-Channel MOSFET Source and Supply to Chip Circuitry. Bypass IN with a 22

µF

capacitor to ground.

2, 3, 6, 11, 14, 15

OUT

Output from P-Channel MOSFET Drain. Bypass OUT with a 0.1

µF capacitor to ground.

7

ON

Digital Input. Active-low switch enable (logic 0 turns the switch on).

9

SET

Current Limit Setting Input. A resistor from set to ground sets the current limit. Refer to

Current Limit section.

10

FAULT

Open-Drain Digital Output.

FAULT goes low when the current limit is exceeded or the die

temperature exceeds 135

°C. During startup, FAULT remains low for the turn-on time + 50 µs.
