PIN FUNCTION DESCRIPTIONS
Function
Input to P-Channel MOSFET Source and Supply to Chip Circuitry. Bypass IN with a 22 µF
capacitor to ground.
Output from P-Channel MOSFET Drain. Bypass OUT with a 0.1 µF capacitor to ground.
Digital Input. Active-low switch enable (logic 0 turns the switch on).
Current Limit Setting Input. A resistor from set to ground sets the current limit. Refer to
Current Limit section.
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.
