Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
GND 1 Ground connection, connect externally to PowerPAD
IN 2,3,4 I Input voltage, connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the IC as possible
EN 5 I Enable input, logic high turns on power switch.
ILIM 6 O External resistor used to set current-limit threshold; recommended. 24.9 kΩ ≤ R(ILIM) ≤ 100 kΩ.
OUT 7,8,9 O Power-switch output
FAULT 10 O Active-low open-drain output, asserted during over-current or overtemperature conditions.
PowerPAD™ PAD Internally connected to GND; used to heat-sink the part to the circuit board traces. Connect PowerPAD to GND pin externally.
