NE56604-42 - System reset

Description

The NE56604-42 is designed to generate a reset signal at a threshold voltage of 4.2 V for a variety of microprocessor and logic systems.

Accurate reset signals are generated during momentary power interruptions, or whenever power supply voltages sag to intolerable levels.

Features

  • Both positive and negative logic reset output signals are available.
  • Accurate threshold detection.
  • Internal power-on reset delay.
  • Internal Watchdog timer programmable with external resistor.
  • Watchdog monitoring time of 100 ms (typical).
  • Reset assertion with VCC down to 0.8 VDC (typical).
  • Few external components required.
