The TPS3760-Q1 is a 65V input voltage detector with 1µA IDD and 1% accuracy, and a fast detection time. This device can be connected directly to 12V / 24V automotive battery system for continuous monitoring of over (OV) or under (UV) voltage conditions; with the internal resistor divider, it 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 signals. Also, CTS functions as a debouncer by ignoring voltage glitches on the monitored voltage rails; CTR operates as a manual reset (MR) that can be used to force a system reset.

The TPS3760-Q1 is available in a 4.1mm×1.9mm SOT 14-pin package. TPS3760-Q1 operates over –40°C to +125°C TA.
