3 Description
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 (V_IT–), and goes high when
the voltage returns above the respective threshold
(V_IT+). 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.
