ADM708RARZ

The ADM708RARZ by AD(RoHS) is a microprocessor supervisory circuit designed to monitor 3 V and 3.3 V power supplies. It provides essential functions for reliable system operation, including power supply monitoring that generates a reset output during power-up, power-down, and brownout conditions. The reset output remains valid even with VCC as low as 1 V.

Key electrical specifications include a precision voltage monitor with a nominal threshold of 3.08 V for the ADM708T variant, a low quiescent current of 100 µA, and a reset pulse width of 200 ms. An independent watchdog timer is also integrated, activating if the watchdog input does not toggle within 1.6 seconds. Additionally, a 1.25 V threshold detector is available for power fail warnings, low battery detection, or monitoring an auxiliary power supply. The ADM708R/S/T variants offer both active high and active low reset outputs.

This component is suitable for critical microprocessor monitoring in various applications such as computers, controllers, intelligent instruments, battery-operated systems, and portable instruments. It is supplied in an 8-SOIC surface mount package, typically on tape and reel for automated assembly processes.
