The ADM823SYRJZ-R7 from Analog Devices is a supervisory circuit that monitors 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 to 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.
Key features include a precision 2.5 V to 5 V power supply monitor with seven reset threshold options ranging from 2.19 V to 4.63 V. The reset timeout is a minimum of 140 ms, and the watchdog timer has a typical timeout of 1.6 seconds. This device consumes only 5 µA of low power, making it suitable for portable applications.
The ADM823SYRJZ-R7 is available in a 5-lead SOT-23-5 package and is specified over the automotive temperature range of -40°C to 125°C. Its guaranteed reset output is valid down to VCC = 1 V, and it offers power supply glitch immunity.
This supervisory circuit is ideal for applications such as microprocessor systems, computers, controllers, intelligent instruments, and portable equipment where reliable power monitoring and system reset are critical.
