NJU7296
SYSTEM RESET IC WITH DELAY CIRCUIT
GENERAL DESCRIPTION
The NJU7296 is a system reset IC with built-in delay circuit that
monitors the status of a power line, and outputs a reset signal to
the microcomputer.
The NJU7296 outputs a reset signal when fall below the detection
voltage.
Delay times are fixed internally and those are set in each of rising
and falling.
It is possible to monitor multiplex power line by combination of
NJU7296 because output voltage VOUT is kept Low level when
EXT Pin is Low level by connecting with other NJU7296.
Detection voltage’s default value is 1.0V. It can be adjusted to
desired voltage by the resistor divider.
In addition, a hysteresis voltage can be set arbitrarily by inserting a
resistor between the VIN pin and the HYS pin.
