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
IT
) or the voltage of
M R
manual reset (
) is pulled to a logic low, the
R E S E T
signal will be asserted. The 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
M R
resistor divider. When SENSE
E
voltage and
R E S T
is driven to a
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
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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T
J
(MAX)-
T
A
)/θ
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7 4-layer board.
