Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Switch enable input controlling the output MOSFET gate; active-high for the -1 variant (this MPN), must be driven to a defined logic level and not left floating or taken above VBIAS or below ground. |
| 2 | /FAULT | output | Active-low open-drain N-channel fault status output that asserts on thermal shutdown or on an overcurrent lasting longer than 28ms, needing an external pull-up to a rail of 6V maximum. |
| 3 | UVLOIN | input | Undervoltage lockout adjust input; left open the UVLO threshold is 1.45V, and an external divider (total resistance below 200kΩ) lowers it for VIN at or below 1.6V. |
| 4 | GND | power_in | Ground connection, tie to analog ground. |
| 5 | ILIM | passive | Current limit set pin where a resistor RSET to ground sets the limit as CLF/RSET (CLF 340A·Ω typical) for a continuous output range of 0.25A to 1.5A. |
| 6 | VBIAS | power_in | Bias supply input powering the internal circuitry with a range of 1.6V to 5.5V, which must be present for the switch to operate and be at least VIN. |
| 7 | VIN | power_in | Switch input supply (drain of the output MOSFET) with a range of 0.8V to 5.5V, which must be externally connected to the other VIN pin (pin 9). |
| 8 | VOUT | power_out | Switch output (source of the output MOSFET), which must be externally connected to the other VOUT pin (pin 10). |
| 9 | VIN | power_in | Switch input supply (drain of the output MOSFET) with a range of 0.8V to 5.5V, which must be externally connected to the other VIN pin (pin 7). |
| 10 | VOUT | power_out | Switch output (source of the output MOSFET), which must be externally connected to the other VOUT pin (pin 8). |
