The TPS37100-Q1 and TPS37102-Q1 are 105V input voltage supervisors with low quiescent current (5uA), fast detection time, and an integrated buffer for supply voltage measurements. This family of devices can connect directly to a 24V / 48V / 72V battery or voltage rail for continuous monitoring of over (OV) or under (UV) voltage conditions. Wide hysteresis voltage options are available to ignore false output deassertions that are be caused by battery voltage transients.

The TPS37100-Q1 and TPS37102-Q1 include two outputs (OUT A and OUT B) that are used as separate OV and UV fault monitors enabling system to take different action based on the fault that occurs. Additionally, the AOUT pin provides a scaled down SENSE pin voltage output and is intended to be sampled by ADC for supply voltage measurements. The user can select the scaling factor desired based on the orderable part selected. The TPS37102-Q1 comes with BIST which is implemented at start-up to verify device health as well as an optional latching feature on OUT A to help the system bring into a safe state when critical faults occurs.
