Working Principles

The MAX6380XR41+TG125 operates by continuously comparing the power supply voltage with the adjustable threshold voltage set by the TH pin. When the voltage falls below the threshold, the RESET pin is asserted, indicating a reset condition. The reset signal remains active for a fixed period of 125ms after the voltage rises above the threshold, allowing sufficient time for the system to initialize properly.

Detailed Application Field Plans

The MAX6380XR41+TG125 is commonly used in various applications where accurate voltage monitoring and reset functionality are required. Some potential application fields include:

1. Battery-powered devices: The low-power operation and adjustable threshold make it suitable for battery-powered devices that require precise monitoring of the battery voltage and automatic reset functionality.
2. Microcontroller systems: The MAX6380XR41+TG125 can be used in microcontroller-based systems to ensure proper initialization and reliable operation by monitoring the power supply voltage and generating a reset signal if necessary.
3. Industrial control systems: In industrial control systems, the MAX6380XR41+TG125 can be used to monitor the power supply voltage and initiate a reset if the voltage drops below a certain threshold, ensuring the system's stability and preventing data corruption.
