DESCRIPTION
The MP640 0 family is the microprocessor (µP)
supervisory circu it w hich can monitor and
provide reset functio n for system voltages fro m
0.4V. Whe n either th e SENSE voltage falls
below its t hresM hR old ( VIT) or the voltage of
mR aE nS uE aT l
reset (

) is pulle d to a logic low, the
be a sserted. The r eset
voltage can be fa ctory-set for stan dard voltage
rails from 0. 9V to 5V, w hile the MP6400DG(J)-

age and
driven to
a
logic high after a user-programmable delay time.
The MP640 0 has a very low quies cent current
of 1.6μA typically, which makes it ideal suitable
for battery-powered application s. It provides a
precision re ference to achieve ±1% threshold
accuracy. The reset delay time can be select ed
by a capacitor which is connect ed between
CDELAY and GND, allowing the user to select any
delay time from 2.1ms to 10s. 380ms delay time
is selected by connecting the C DELAY pin to V CC,
while 24ms delay time by leaving the C DELAY pin
float. MP6400 is available in TSOT23 and
2mm×2mm 6-pin QFN packages.
FEATURES
• Fixed Threshold Volta ges for Standard
Voltage Rails From 0.9V to 5V and
