SYSTEM RESET IC WITH DELAY CIRCUIT

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJU7295 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 NJU7295 outputs a reset signal when exceeds the detection

voltage. Therefore it is possible to control the microcomputer by

detecting a rising edge of a power line.

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

EXT Pin is Low level by connecting with other NJU7295.

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
