Reset Timing at Power-ON
LV25700PM
Vcop_H
Power supplies must be
applied after Low level
input to RESET (Pin 33)
is established.
VDDBUS
Vcop_L/VDDLOGIC
RESET (Low level depends on VDDBUS.)
Input Low level to RESET starting from before power is
applied until 50ms (tPOR) or more after power is stabilized.
tPOR
tCKR
GND_VSS
The power supplies must be applied in the order of 8V to 5V. (can also be applied simultaneously.)
In case the RESET pin is left open, perform pull-down or other pin treatment.
Reset Timing at Instantaneous Power Failure
Vcop_H
VDDBUS Vcop_L/VDDLOGIC
3.5V
Input Low level to RESET when the
VDDLOGIC voltage falls to 3.5V or less.
Input Low level to RESET starting from
when the instantaneous power failure is
detected until 50ms (tPDR) or more after
the power supply is stabilized.
Reset Timing at Power-OFF
Vcop_H
tPDR
tCKR
GND_VSS
The power supplies must be turned off in the order of 5V to 8V.
(can also be turned off simultaneously.)
Vcop_L/VDDLOGIC VDDBUS
3.5V
Input Low level to RESET when the
VDDLOGIC voltage falls to 3.5V or less.
Input Low level to RESET during power off.
GND_VSS
