Pin Configuration

The MAX6314US31D3-T has a SOT23-3 package with the following pin configuration:

  1. GND: Ground connection
  2. RESET: Active-low reset output
  3. VCC: Power supply input

Functional Features

  • Accurate voltage monitoring: The MAX6314US31D3-T ensures reliable system operation by monitoring the power supply voltage.
  • Reset output: It provides an active-low reset signal when the monitored voltage falls below the threshold.
  • Adjustable/reset timeout period: The reset timeout period can be adjusted or set to a fixed value, allowing flexibility in system design.

Advantages and Disadvantages

Advantages

  • Low-power consumption: The IC operates at a quiescent current of only 1µA, making it suitable for battery-powered applications.
  • Precision voltage monitoring: The device offers precise voltage monitoring with various threshold voltage options.
  • Small form factor: The SOT23-3 package allows for space-efficient integration into compact designs.

Disadvantages

  • Limited reset timeout options: The available reset timeout periods may not cater to all specific application requirements.
  • Single-channel monitoring: The IC can monitor only one power supply voltage at a time, limiting its use in systems with multiple power sources.

Working Principles

The MAX6314US31D3-T operates by comparing the input voltage (VCC) with the selected threshold voltage. When VCC falls below the threshold, the reset output (RESET) is activated, indicating a power failure or an out-of-range condition. The reset signal remains active until VCC rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX6314US31D3-T finds applications in various fields, including:

  1. Battery-powered devices: It ensures proper operation by monitoring the battery voltage and initiating a reset if necessary.
  2. Microcontroller-based systems: The IC provides a reliable reset signal to microcontrollers during power-up or voltage fluctuations.
  3. Industrial automation: It can be used to monitor power supply voltages in control systems, ensuring uninterrupted operation.
