NE56605-42 - System reset

Description

The NE56605-42 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 capacitor.
  • Watchdog monitoring time of 10 ms.
  • Reset assertion with VCC down to 0.8 VDC (typical).
  • Few external components required.
