3 Description
The TPS386000-Q1 family of voltage supervisors can
monitor four power rails that are greater than 0.4 V
and one power rail less than 0.4 V (including negative
voltage) with a 0.25% (typical) threshold accuracy.
Each of the four supervisory circuits (SVS-n) assert a
RESETn or RESETn output signal when the
SENSEm input voltage drops below the programmed
threshold. With external resistors, the threshold of
each SVS-n can be programmed (where n = 1, 2, 3,
4 and m = 1, 2, 3, 4L, 4H).
Each SVS-n has a programmable delay before
releasing RESETn or RESETn. The delay time can
be set from 1.4 ms to 10 s through the CTn pin
connection. Only SVS-1 has an active-low manual
reset (MR) input; a logic-low input to MR asserts
RESET1 or RESET1.
SVS-4 monitors the threshold window using two
comparators. The extra comparator can be
configured as a fifth SVS to monitor negative voltage
with voltage reference output VREF.
The TPS386000-Q1 device has a very low quiescent
current of 12 μA (typical) and is available in a small,
4-mm x 4-mm, VQFN-20 package.
