## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GNDA | power_in | Ground for the IN1 and IN2 switches and their circuitry. |
| 2 | IN1 | input | N-channel MOSFET drain of power switch 1; the device operates from VI(IN) = 2.7 V to 5.5 V. |
| 3 | IN2 | input | N-channel MOSFET drain of power switch 2; the device operates from VI(IN) = 2.7 V to 5.5 V. |
| 4 | EN1 | input | Enable input for switch 1; active low turns on the power switch, with VI(EN) rated 0 V to 5.5 V. |
| 5 | GNDB | power_in | Ground for the IN3 and IN4 switches and their circuitry. |
| 6 | IN3 | input | N-channel MOSFET drain of power switch 3; the device operates from VI(IN) = 2.7 V to 5.5 V. |
| 7 | IN4 | input | N-channel MOSFET drain of power switch 4; the device operates from VI(IN) = 2.7 V to 5.5 V. |
| 8 | EN3 | input | Enable input for switch 3; active low turns on the power switch, with VI(EN) rated 0 V to 5.5 V. |
| 9 | EN4 | input | Enable input for switch 4; active low turns on the power switch, with VI(EN) rated 0 V to 5.5 V. |
| 10 | OUT4 | output | Power-switch output for switch 4, with continuous current limited to 500 mA per switch. |
| 11 | OUT3 | output | Power-switch output for switch 3, with continuous current limited to 500 mA per switch. |
| 12 | OCB | output | Overcurrent indicator for switch 3 and switch 4; active-low open-drain output, sink current 10 mA at VO = 5 V. |
| 13 | EN2 | input | Enable input for switch 2; active low turns on the power switch, with VI(EN) rated 0 V to 5.5 V. |
| 14 | OUT2 | output | Power-switch output for switch 2, with continuous current limited to 500 mA per switch. |
| 15 | OUT1 | output | Power-switch output for switch 1, with continuous current limited to 500 mA per switch. |
| 16 | OCA | output | Overcurrent indicator for switch 1 and switch 2; active-low open-drain output, sink current 10 mA at VO = 5 V. |
