• Provides a reset signal on the RESET pin when the voltage crosses the threshold
• Manual reset option available through the MR pin
• Adjustable reset timeout period for flexibility in application

Advantages and Disadvantages

Advantages: - High accuracy voltage monitoring - Low power consumption - Adjustable reset timeout period - Manual reset option for added control

Disadvantages: - Limited threshold voltage options - No built-in hysteresis

Working Principles

The MAX6381XR16D3-T is a voltage monitor IC that operates by comparing the voltage on the TH pin with a preset threshold voltage. When the voltage on the TH pin crosses the threshold, the RESET pin is activated, providing a reset signal to the system. The reset timeout period can be adjusted to meet specific application requirements. The MR pin allows for manual reset, giving additional control over the reset function.

Detailed Application Field Plans
