Working Principles

The MAX6313UK34D3-T is designed to monitor the voltage level of a power supply. It compares the supply voltage with a set threshold voltage and generates a reset signal when the voltage falls below this threshold. The threshold voltage can be adjusted using external resistors, allowing customization for different applications.

The IC operates with low quiescent current, ensuring minimal power consumption. It also offers the option to set a fixed or adjustable reset timeout period. This timeout period determines how long the reset signal remains active after the voltage rises above the threshold again.

Detailed Application Field Plans

The MAX6313UK34D3-T finds applications in various fields where voltage monitoring and system reset functionality are required. Some potential application areas include:

1. Battery-powered devices: Ensuring proper operation by monitoring battery voltage and initiating a reset if it drops below a critical level.
2. Microcontroller systems: Providing a reliable reset signal to restart the system in case of power supply fluctuations or brownouts.
3. Industrial automation: Monitoring power supply voltages in control systems to prevent malfunctions and ensure safe operation.
4. Automotive electronics: Protecting sensitive components from voltage dips or spikes by triggering a reset when necessary.
5. IoT devices: Enhancing the reliability of connected devices by monitoring power supply integrity and initiating resets if needed.
