NJU7295 - SYSTEM RESET IC

Description

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.

NJU7295 SYSTEM RESET IC WITH DELAY CIRCUIT ■ GENERAL DESCRIPTION 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 NJU7295 because output voltage VOUT is kept High level when 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.
