DESCRIPTION
The MP6400 family is the microprocessor (µP)
supervisory circuit which can monitor and
provide reset function for system voltages from
0.4V. When either the SENSE voltage falls
below its threshold (V
manual reset (
voltage can be factory-set for standard voltage
rails from 0.9V to 5V, while the MP6400DG(J)-
01 reset voltage is adjustable with an external
resistor divider. When SENSE voltage and
exceed their thresholds,
logic high after a user-programmable delay time.
The MP6400 has a very low quiescent current
of 1.6μA typically, which makes it ideal suitable
for battery-powered applications. It provides a
precision reference to achieve ±1% threshold
accuracy. The reset delay time can be selected
by a capacitor which is connected between
C
delay time from 2.1ms to 10s. 380ms delay time
is selected by connecting the C
while 24ms delay time by leaving the C
float. MP6400 is available in TSOT23 and
2mm×2mm 6-pin QFN packages.
