Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
EN1 4 I Enable input, logic high turns on channel one power switch
EN2 5 I Enable input, logic high turns on channel two power switch
GND 1 Ground connection; connect externally to PowerPAD
IN 2, 3 I Input voltage; connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the IC as possible.
FAULT1 10 O Active-low open-drain output, asserted during overcurrent or overtemperature condition on channel one.
FAULT2 6 O Active-low open-drain output, asserted during overcurrent or overtemperature condition on channel two
OUT1 9 O Power-switch output for channel one
OUT2 8 O Power-switch output for channel two
ILIM 7 O External resistor used to set current-limit threshold; recommended 20 kΩ ≤ RILIM ≤ 187 kΩ.
PowerPAD™ PAD Internally connected to GND; used to heat-sink the part to the circuit board traces. Connect PowerPAD to GND pin externally.
