Pins, by the datasheet

6
1 ENABLE
Active-high enable; low immediately drives SENSE_OUT low, and high permits assertion after the capacitor-adjustable delay when SENSE exceeds its threshold. · p. 4
2 GND
Ground. · p. 4
3 SENSE
Monitored voltage input through an external resistor; assertion threshold is 0.5 V with hysteresis on falling voltage. · p. 4
4 SENSE_OUT
Output goes low when SENSE falls below threshold minus hysteresis or ENABLE is low; requires a pullup and supports pullup voltages up to 18 V independent of VCC. · p. 4
5 CT
Connect a ground-referenced capacitor to set the delay from SENSE or ENABLE assertion to SENSE_OUT assertion. · p. 4
6 VCC
Supply input for 1.7 V to 6.5 V; place a 0.1-uF ceramic capacitor close to this pin. · p. 4
