Description and Introduction
Low Cost 礟 Supervisor with 4.65V Threshold Voltage, Power Fail and Watchdog Features and Active Low and High Reset Outputs The ADM707 is a microprocessor supervisory circuit manufactured by Analog Devices. It is designed to monitor the power supply voltage of microprocessor and digital systems. The ADM707 provides three key functions:
1. **Reset Output**: The ADM707 asserts a reset signal when the power supply voltage drops below a specified threshold, ensuring the microprocessor starts in a known state. The reset signal remains active for a minimum period after the power supply returns to the valid operating range. 2. **Power-On Reset**: The device generates a reset pulse upon power-up, ensuring the microprocessor initializes correctly. 3. **Watchdog Timer**: The ADM707 includes a watchdog timer that monitors the activity of the microprocessor. If the microprocessor fails to toggle the watchdog input within a specified time, the ADM707 asserts a reset signal to restart the system. ### Key Specifications: The ADM707 is commonly used in applications requiring reliable power supply monitoring and microprocessor reset functionality, such as embedded systems, industrial controls, and automotive electronics. |
