The TPS3762-Q1 is a 65 V input voltage supervisor with 4 µA I DD, 0.8% accuracy, fast detection time, and a built-in self-test feature. This device can be connected directly to 12 V / 24 V automotive battery system for continuous monitoring of overvoltage (OV) or undervoltage (UV) conditions; with its internal resistor divider, TPS3762-Q1 offers the smallest total solution size. Wide hysteresis voltage options are available to ignore cold crank, start-stop and various car battery 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 automotive 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 rising and falling edges of the RESET signal. The CTS functions as a debouncer by ignoring voltage glitches on the monitored voltage rails.

The TPS3762-Q1 is available in a 2.9 mm × 1.6 mm SOT23 8-pin package. TPS3762-Q1 operates over -40°C to +125°C T A.
