ADM823SYKSZ-R7

监控电路，带有看门狗和手动复位功能5引脚SC70和SOT -23 Supervisory Circuits with Watchdog and Manual Reset in 5-Lead SC70 and SOT-23

The ADM823 series Supervisory Circuit with watchdog timer and manual reset input. The ADM823/ADM824/ADM825 are supervisory circuits that monitors the power supply voltage levels and code execution integrity in microprocessor-based systems. In addition to providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by an external push-button, through a manual reset input. The reset and watchdog timeout periods are fixed at 140ms minimum and 1.6 seconds typical, respectively.
