MPQ6400-AEC1
Low Quiescent Current
Programmable-Delay Supervisory Circuit
Available in AEC-Q100
DESCRIPTION
The MPQ6400 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_IT) or the voltage of
manual reset (MR ) is pulled to a logic low, the
RESET ^{signal will be asserted. The reset}
voltage can be factory-set for standard voltage
rails from 0.9V to 5V, while the MPQ6400DG-
01 reset voltage is adjustable with an external
resistor divider. When SENSE voltage and MR
exceed their thresholds, _RESET is driven to a
logic high after a user-programmable delay
time.
The MPQ6400 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 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. MPQ6400 is available in 2mm×2mm 6-pin
QFN package.
