The MIC803-40D2VM3TR is a voltage supervisory circuit manufactured by Micrel (now Microchip Technology). It is designed to monitor the voltage level of a power supply and provide a reset signal to a microcontroller or other digital system when the voltage falls below a specified threshold. This ensures that the system operates correctly and prevents data corruption during brownout conditions.

Additional Details
The MIC803-40D2VM3TR has a threshold voltage of 4.0V. The active-low reset output remains asserted until the supply voltage rises above the threshold. The device’s low quiescent current makes it suitable for battery-powered applications. The small package size allows for easy integration into compact circuit designs. By providing a reliable reset signal, the MIC803-40D2VM3TR helps to prevent unpredictable system behavior and ensures proper system startup and operation.
