ViewTable 6-1 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 device 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. |
