The TPS3710 wide-supply voltage detector operates over a 1.8-V to 18-V range. The device has a high-accuracy comparator with an internal 400-mV reference and an open-drain output rated to 18 V for precision voltage detection. The monitored voltage can be set with the use of external resistors.
The OUT pin is driven low when the voltage at the SENSE pin drops below (VIT–), and goes high when the voltage returns above the respective threshold (VIT+). The comparator in the TPS3710 includes built-in hysteresis for filtering to reject brief glitches, thereby ensuring stable output operation without false triggering.
The TPS3710 is available in a SOT-6 package, and a 1.5-mm × 1.5-mm WSON-6 package, and is specified over the junction temperature range of –40°C to +125°C.
