GND 2 2 5 5 — Ground, connect to external exposed pad. EN 3 — 4 — I Enable input, logic low turns on power switch. EN — 3 — 4 I Enable input, logic high turns on power switch. FAULT 4 4 3 3 O Active-low open-drain output, asserted during over- current, over-temperature, or reverse-voltage conditions. ILIM 5 5 2 2 O Use external resistor to set current-limit threshold; recommended 10k Ω≦RLIM≦232kΩ. OUT 6 6 1 1 O Output Exposed Pad — — Pad Pad — No internal connection; recommend to connect to GND externally for improved power dissipation. |
