NJU7296

System Reset IC with Delay Circuit

Features
  • High Precision Detection Voltage (±1.0% (Ta=25°C))
  • Detection Voltage (1.0V (default) and adjustable with external resistor)
  • Reset Output Logic (
    Reset Low output when VIN pin is detection voltage or below
    *If required reset low output when VIN pin is detection voltage or more, see the NJU7295.)
  • Delay Circuit (Internal Fixed type) (Rising / Falling independent setting)
  • Ultra Low Quiescent Current (1.7µA typ.)
  • Supply Voltage Range (1.5 to 5.5V)
  • External Input pin (While inputting low signal, keep output Low level)
  • Adjustable Hysteresis Voltage
  • Output Type (CMOS output)
  • Package (SOT-23-6-1)
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.
