Description

The ADM6823TYRJZ is a supervisory circuit designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. It provides power-on reset signals and includes an on-chip watchdog timer that can reset the microprocessor if it fails to strobe within a preset timeout period. The ADM6823TYRJZ also allows for a reset signal to be asserted through an external push-button using a manual reset input. This electronic component is available in a 5-lead SOT-23 package.
