The TPS3762 is a 65 V input voltage supervisor with 4 µA IDD, 0.9% accuracy, fast detection time, and a Built-In Self-Test feature. This device can be connected directly to 12 V / 24 V industrial SELV power rails for continuous monitoring of overvoltage (OV) and undervoltage (UV) conditions; with its internal resistor divider, TPS3762 offers the smallest total solution size. Wide hysteresis voltage options are available to ignore large voltage transients. Built-in hysteresis on the SENSE pin prevents false reset signals when monitoring a supply voltage rail.

The separate VDD and SENSE pins allow redundancy sought by high-reliability systems and SENSE can monitor higher and lower voltages than VDD. Optional use of external resistors are supported by the high impedance input of the SENSE pin. CTS and CTR pins allow delay adjustability on the falling and rising edges of the RESET signal. The CTS functions as a debouncer by ignoring voltage glitches on the monitored voltage rails.

The TPS3762 is available in a 2.9 mm × 1.6 mm SOT23 8-pin package. TPS3762 operates over -40°C to +150°C TA.
