The TPS3762-Q1 is a family of 65V input voltage supervisor with 4µA IDD, 0.9% accuracy, fast detection time (3µs) and a Built-In Self-Test feature. This family of devices can be connected directly to 12V / 24V automotive battery systems for continuous monitoring of overvoltage (OV) and undervoltage (UV) conditions. Wide hysteresis voltage options are available to ignore large voltage transients and prevent false reset signals.
The TPS3762-Q1 output (Reset) that is used for OV and UV faults enabling system to take action if a fault occurs. The TPS3762-Q1 comes with BIST which is implemented at start-up to verify device health as well as an optional latching feature to help the system bring into a safe state when critical faults occurs.
