ADM823LYRJZ-R7

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.

• Power supply glitch immunity
• Specified over automotive temperature range
• Guaranteed reset output valid to VCC=1V
• 5μA Low power consumption
