The ADM1191-2ARMZ-R7 is an IC (integrated circuit) component designed by Analog Devices Inc. It is a system supervisor and watchdog timer with a built-in reset controller. Below is an overview of its key features:
1. System Supervision: The ADM1191-2ARMZ-R7 provides comprehensive system monitoring and supervision functions. It monitors critical system voltages and currents, allowing for protection against undervoltage, overvoltage, and overcurrent conditions.
2. Adjustable Voltage Monitoring: This IC can detect and monitor voltage levels on up to eight channels. The voltage thresholds can be easily programmed according to the requirements of the application.
3. Programmable Current Monitoring: The ADM1191-2ARMZ-R7 allows monitoring of current flow on up to four channels. It offers adjustable current thresholds and accurate current measuring capabilities.
4. Watchdog Timer: It incorporates a watchdog timer function to ensure the system remains operational. It monitors the activity of the system's microcontroller or microprocessor and restarts it if it becomes unresponsive.
5. Reset Controller: The IC includes an integrated reset controller, which generates a system reset signal during power-up and power-down events. The reset signal ensures that the system initializes properly and avoids system instability.
6. Fault Logging and Reporting: It can log and report fault conditions, providing valuable information for diagnosing system errors. The fault logging feature can aid in troubleshooting and improving system reliability
