Introduction

AI Translation

The ADM691A/ADM693A/ADM800L/ADM800M family of supervisory circuits offers complete single chip solutions for power supply monitoring and battery control functions in microprocessor systems. These functions include μP reset, backup - battery switchover, watchdog timer, CMOS RAM write protection, and power - failure warning. The family of products provides an upgrade for the MAX691A/93A/800M family of products. All parts are available in 16 - pin DIP and SO packages. The ADM691A is also available in a space - saving TSSOP package. The following functionality is provided:

  • Power - on reset output during power - up, power - down and brownout conditions. The circuitry remains operational with VCC as low as 1V
  • Battery backup switching for CMOS RAM, CMOS microprocessor or other low power logic.
  • A reset pulse if the optical watchdog timer has not been toggled within a specified time.
  • A 1.25V threshold detector for power fail warning, low battery detection, or to monitor a power supply other than +5V
