ADM708ARZ

The ADM708 series Supervisory Circuit that can be suitable for monitoring 5V power supplies/batteries and microprocessor activity. The ADM705/ADM706 provides power-supply monitoring circuitry that generates a reset output during power-up, power-down and brownout conditions. The reset output remains operational with VCC as low as 1V. Independent watchdog monitoring circuitry is also provided. This is activated if the watchdog input has not been toggled within 1.60 seconds. In addition, there is a 1.25V threshold detector to warn of power failures, to detect low battery conditions or to monitor an additional power supply. An active low, debounced manual reset input (MR) is also included.

• Debounced TTL/CMOS manual reset input (MR)
• Active high reset output
• Voltage monitor for power-fail or low-battery warning
• Superior upgrade for MAX705 to MAX708
• 190µA Quiescent current
