MB3793-28A - Power-Voltage Monitoring IC

Description

The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer.

A reset signal is output when the power is cut or falls abruptly.

Features

  • Precise detection of power voltage fall: ±2.5%.
  • Detection voltage with hysteresis.
  • Low power dispersion: ICC = 41 μA (Typ).
  • Internal dual-input watchdog timer.
  • Watchdog timer halt function.
  • Independently-set watchdog and reset times.

MB3793-28A Description Power-Voltage Monitoring IC with Watchdog Timer Datasheet The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer. A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting, a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for system operation diagnosis can provide a fail-safe function for various application systems. Model No. MB3793-28A Marking Code 3793AR Detection voltage 2.8 V Features ■ Precise detection of power voltage fall: ±2.
