The ADM823SYRJZ-R7 is an IC (integrated circuit) component manufactured by Analog Devices Inc. It is a supervisory circuit with a power supply voltage monitor and a watchdog timer. Here are its key features:
1. Power Supply Voltage Monitor: The ADM823SYRJZ-R7 is designed to monitor the power supply voltage and provide various functions based on the voltage levels. It can detect voltage rise and fall conditions, and can generate reset signals to the microcontroller when the power supply voltage falls below or rises above a specified level.
2. Watchdog Timer: This IC component also includes a watchdog timer feature, which ensures that the microcontroller or system is running properly. It requires periodic triggering by the system to prevent it from resetting. If the microcontroller fails to provide the required trigger within a specific time frame, the watchdog timer will reset the microcontroller, preventing it from hanging or running incorrectly.
3. Adjustable Reset Threshold: The ADM823SYRJZ-R7 allows the user to set the reset threshold voltage using external resistors, giving flexibility in defining the power supply voltage level at which the reset signal will be generated.
4. Reset Timeout Period: The component has a programmable reset timeout period, which can be adjusted using an external capacitor. This feature allows customization of the time period for which the reset signal will be asserted after a power-on or voltage fault condition is detected
