## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Power-switch output of the 70-mΩ N-channel high-side MOSFET, with a continuous output current of 0 to 500 mA recommended. |
| 2 | GND | power_in | Ground reference for the device; all voltages are specified with respect to GND. |
| 3 | OC | output | Open-drain overcurrent output, asserted active low on overcurrent or overtemperature, with VOL of 0.4 V maximum at IO(OC) = 5 mA. |
| 4 | EN | input | Enable input where logic low turns on the power switch; VIH is 2 V minimum and VIL is 0.8 V maximum for 2.7 V ≤ VI(IN) ≤ 5.5 V, with VI(EN) rated 0 to 5.5 V. |
| 5 | IN | input | Input voltage pin for the power switch, rated 2.7 V to 5.5 V recommended with an absolute maximum of -0.3 V to 6 V. |
