Pin Configuration

The MAX6314US25D1+T has a total of 5 pins:

  1. GND: Ground connection.
  2. MR: Manual reset input pin. When pulled low, it forces a reset condition.
  3. RESET: Active-low reset output. It goes low when the monitored voltage falls below the threshold.
  4. VCC: Power supply input.
  5. TH: Threshold voltage selection pin. Connect to VCC or GND to set the desired threshold voltage.

Functional Features

  • Monitors the power supply voltage continuously.
  • Generates a reset signal when the voltage falls below the threshold.
  • Adjustable reset timeout period allows customization for specific applications.
  • Manual reset input provides a way to force a reset condition externally.

Advantages and Disadvantages

Advantages: - Enhances system reliability by ensuring proper initialization. - Adjustable reset timeout period allows flexibility in different applications. - Small package size (SOT23-5) enables space-saving designs.

Disadvantages: - Limited threshold voltage options (2.5V in this model). - Requires an external manual reset input for forced reset conditions.

Working Principles

The MAX6314US25D1+T operates by continuously monitoring the power supply voltage through the VCC pin. When the voltage falls below the threshold set by the TH pin, the RESET pin goes low, indicating a reset condition. The reset timeout period can be adjusted to meet specific application requirements. Additionally, the MR pin allows for a manual reset input, which forces a reset condition when pulled low.
