Disadvantages: - Limited reset timeout period - Only available in tape and reel packaging

Working Principles

The MAX823MEXK+T is designed to monitor the supply voltage of a system. It compares the input voltage with a reference voltage and generates a reset signal when the voltage drops below the specified threshold. The reset output remains low until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX823MEXK+T is commonly used in various applications, including:

1. Battery-powered devices: Ensures proper operation by monitoring the battery voltage and initiating a reset if it falls below the threshold.
2. Microcontroller systems: Provides a reliable reset signal to the microcontroller during power-up or voltage fluctuations.
3. Industrial equipment: Monitors the power supply voltage to prevent malfunctions or data corruption.
