NJU7295 Datasheet | New Japan Radio

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 microputer. The NJU7295 outputs a reset signal when exceeds the detection voltage. Therefore it is possible to control the microputer 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 bination 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. In addition, a hysteresis voltage can be set arbitrarily by inserting a resistor between the VIN pin and the HYS pin. - PACKAGE OUTLINE NJU7295F1 - FEATURES - High Precision Detection Voltage - Detection Voltage - Reset Output Logic - Delay Circuit (Internal Fixed type) - Ultra Low Quiescent Current - Supply Voltage Range - External Input Pin - Adjustable Hysteresis Voltage - Output Type - Package 1.0% (Ta=25 C) 1.0V (default) and adjustable with external resistor Reset Low output when VIN pin is detection voltage or more - If required reset low output when VIN pin is detection voltage or below, see the NJU7296.
