3 Description
The TPS386596 device monitors four power rails and
asserts the RESET signal when any of the SENSE
inputs drop below the respective thresholds. SVS-1
can be used to monitor a 3.3-V 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 0.4 V. All SENSE inputs have a threshold
accuracy of 0.25% (typical). The TPS386596L33 also
has an active-low manual reset (MR) that can assert
the RESET signal as desired by the application. The
open-drain, active-low RESET output deasserts after
a fixed 50-ms delay.
The TPS386596 has a low quiescent current of 7 µA
(typical) and is available in a space-saving, 8-pin
MSOP package.
