3 Description
The TPS3860x0 family of supply voltage supervisors
(SVSs) 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 independently for each SVS 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 TPS3860x0 has a very low quiescent current of
11 μA (typical) and is available in a small, 4-mm x 4-
mm, VQFN-20 package.
