DESCRIPTION
The TPS386596L33 monitors four power rails and
asserts the RESET signal when any of the SENSE
inputs drop below their respective thresholds. SVS-1
can be used to monitor a 3.3V nominal power supply
with no external components required. SVS-2, SVS-3,
and SVS-4 are adjustable using external resistors
and can be used to monitor any power supply voltage
higher than 0.4V. All SENSE inputs have a threshold
accuracy of 0.25% (typical). The TPS386596L33 also
has an active low Manual Reset (MR) that can be
used to assert the RESET signal as desired by the
application. The open drain, active low RESEToutput
de-asserts using a fixed 50ms delay.
The TPS386596L33 has a low quiescent current of
7µA typical and is available in a space saving 8-pin
MSOP package.
