EN | 3 | – | 4 | – | I | Enable input, logic low turns on power switch |
EN | – | 3 | – | 4 | I | Enable input, logic high turns on power switch |
GND | 2 | 2 | 5 | 5 | Connect ground connection externally to POWER PAD | |
IN | 1 | 1 | 6 | 6 | I | Input voltage; connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
FAULT | 4 | 4 | 3 | 3 | O | Active-low open-drain output, asserted during overcurrent, overtemperature, or reverse-voltage conditions. |
OUT | 6 | 6 | 1 | 1 | O | Power-switch output |
ILIM | 5 | 5 | 2 | 2 | I | External resistor used to set current-limit threshold; recommended 14.3 kΩ ≤ RILIM ≤ 80.6 kΩ. |
PowerPAD™ | – | – | PAD | PAD | Internally connected to GND; used to heat-sink the part to the circuit board traces, connect to GND pin. |
