Working Principles

The MIC1232N is designed to monitor the supply voltage of a system. It continuously compares the voltage at the TH terminal with a precise internal reference voltage. If the supply voltage drops below the threshold voltage, the reset output is activated, indicating a power failure or an out-of-range condition.

The timeout feature ensures that the reset signal remains active for a minimum period of 140ms after the supply voltage returns to normal. This prevents false resets caused by short power interruptions or voltage fluctuations.

Detailed Application Field Plans

The MIC1232N is commonly used in various electronic systems where reliable power supply monitoring and system reset functionality are required. Some typical application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial control systems
