3 Description
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 be
connected 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 choose 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.
