Working Principles

The MAX6419UK29+T is designed to monitor the supply voltage of a system. It compares the supply voltage with the selected threshold voltage and generates a reset signal when the supply voltage falls below the threshold. The manual reset input allows for external control of the reset function. The active-low reset output remains asserted until the supply voltage rises above the threshold, ensuring proper system initialization.

Detailed Application Field Plans

• Battery-powered devices: Provides low-power voltage monitoring and reset functionality for portable electronics, such as smartphones, tablets, and wearables.
• Microcontroller-based systems: Ensures reliable system initialization by monitoring the power supply voltage and generating a reset signal when necessary.
• Industrial automation: Can be used in various industrial applications where voltage monitoring and reset generation are critical for system reliability.
