Working Principles
The MIC1832N is designed to monitor the supply voltage of a system and provide a reset signal when the voltage falls below a certain threshold. It operates by comparing the supply voltage with an internally set reference voltage. When the supply voltage drops below the threshold, the reset output becomes active-low, indicating a system reset condition. The threshold voltage can be adjusted using the TH pin to suit different application requirements.
