• Provides an active-low reset output that remains low until the supply voltage rises above the threshold voltage for the specified timeout period.
• Offers a manual reset input for immediate system reset.
• Adjustable threshold voltage options allow customization based on specific application requirements.

Advantages and Disadvantages

Advantages

• Low-power consumption, suitable for battery-powered applications.
• Precision monitoring ensures reliable system operation.
• Adjustable threshold voltage allows flexibility in different voltage level monitoring scenarios.
• Small SOT23-5 package saves board space.

Disadvantages

• Limited threshold voltage options may not cover all possible voltage monitoring needs.
• Reset timeout period options might not be suitable for certain applications requiring longer or shorter reset delays.

Working Principles

The MAX6313UK27D2-T operates by continuously monitoring the supply voltage connected to its VCC pin. When the voltage falls below the selected threshold voltage, the IC generates an active-low reset signal on the RESET pin. This reset signal remains low until the supply voltage rises above the threshold voltage for the specified timeout period. The manual reset input (MR) allows immediate system reset when triggered.

Detailed Application Field Plans

The MAX6313UK27D2-T is commonly used in various applications where voltage monitoring and system reset functionality are required. Some typical application fields include:

1. Battery-Powered Devices: Portable electronics, IoT devices, wearable devices.
2. Embedded Systems: Microcontrollers, digital signal processors, FPGA/CPLD-based systems.
3. Industrial Control Systems: PLCs, motor control units, power supplies.
4. Automotive Electronics: Engine control units, infotainment systems, safety modules.
5. Communication Equipment: Routers, switches, network appliances.
