Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | VCC is the power supply input, monitored during startup and normal operation, and should be decoupled to ground with a 0.1 µF capacitor placed as close to the device as possible. |
| 2 | SR | input | Smart Reset button input with a factory-trimmed voltage detector and ±8 kV HBM ESD protection; it is usually connected to GND through a push-button, must not be grounded permanently, and is monitored for a falling edge after power-up. |
| 3 | VREF | power_out | Precise 1.5 V voltage reference specified with 1% accuracy, which requires a mandatory capacitor on the output even when unused (1 µF recommended). |
| 4 | PSHOLD | input | Input with a factory-trimmed voltage detector used to confirm power-up or initiate shutdown, with an internal pull-down during startup, where forcing it low during normal operation deasserts the enable output. |
| 5 | CSRD | passive | Smart Reset delay time input where a capacitor to ground sets the additional delay tSRD, and the pin should be left open if no capacitor is used. |
| 6 | PB | input | Power ON push-button input with a factory-trimmed voltage detector and ±8 kV HBM ESD protection, which must be switched to GND and has an internal 100 kΩ pull-up resistor. |
| 7 | VCCLO | output | High threshold (VTH+) detection output that is active-low and open drain by default, goes low when VCC is below VTH+ or during undervoltage, and requires a pull-up resistor (10 kΩ is sufficient in most applications). |
| 8 | PBOUT | output | Status output of the PB input that is active-low and open drain by default, stays low for at least tINT_Min after a valid press, ignores PB during undervoltage, and requires a pull-up resistor (10 kΩ is sufficient in most applications). |
| 9 | EN | output | Enable output asserted high after a valid turn-on is detected and confirmed, released low if the push-button is released before PSHOLD goes high, PSHOLD is driven low in normal operation, or an undervoltage or long push condition occurs as applicable; it is push-pull by default. |
| 10 | RST | output | Active-low open drain reset output that pulls low for tREC (240 ms min. per the product selector) during startup and, for the option asserting reset after long push, after a long push; it requires a pull-up resistor (10 kΩ is sufficient in most applications). |
| 11 | INT | output | Active-low open drain interrupt output driven low for at least tINT_Min when VCC falls below VTH- or when the push-button is held for tDEBOUNCE or more during normal operation, and it requires a pull-up resistor (10 kΩ is sufficient in most applications). |
| 12 | GND | power_in | Ground reference pin for the device. |
| 13 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
