Key Features

  • Precision supply voltage monitoring with thresholds at 2.63 V, 2.93 V, and 3.08 V for different models.
  • Low quiescent current of 100 µA.
  • 200 ms reset pulse width to ensure proper system initialization.
  • Independent watchdog timer with a 1.6 sec timeout to monitor system activity.
  • Debounced manual reset input (MR) for reliable reset generation.
  • Power fail input (PFI) with a 1.25 V threshold for low battery detection or additional power supply monitoring.
  • Reset output remains operational with VCC as low as 1 V.

Applications

  • Microprocessor and microcontroller systems requiring reliable power supply monitoring.
  • Embedded systems, especially those operating in harsh environments.
  • Low power consumption devices where quiescent current is critical.
  • Systems needing watchdog timer functionality to prevent system lockups.
  • Battery-powered devices requiring low battery detection and power fail warnings.
