PINI/ODESCRIPTION
NO.NAME
1UVOActive-low, open-drain undervoltage output. This pin goes low when the SENSE voltage falls below the internally set undervoltage threshold (VIT–). See the timing diagram in Figure 5-1 for more details. Connect this pin to a pull-up resistor terminated to the desired pull-up voltage.
2GND—Ground
3SENSEIInput for the monitored supply voltage rail. When the SENSE voltage goes below the undervoltage threshold, the UV pin is driven low.
When the SENSE voltage goes above the overvoltage threshold, the OV pin is driven low.
4SETIUse this pin to configure the threshold voltages.
Refer to Table 10-1 for the desired configuration.
5VDDISupply voltage input pin. To power the device, connect a voltage supply (within the range of 2V and 18V) to VDD.
Good analog design practice is to place a 0.1μF ceramic capacitor close to this pin.
6OVOActive-low, open-drain overvoltage output. This pin goes low when the SENSE voltage rises above the internally set overvoltage threshold (VIT+). See the timing diagram in Figure 5-1 for more details. Connect this pin to a pull-up resistor terminated to the desired pull-up voltage.
