Микросхемы и комплектующие ADM823TYRJZ-R7

Схема контроля микропроцессора 1.2В-5.5В питание , 3.08В, 200мс, активный низкий, SOT-23-5

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
