Functional Features

  • Voltage Monitoring: Monitors the input voltage and compares it with the selected threshold voltage.
  • Reset Generation: Generates a reset signal when the monitored voltage falls below the threshold voltage.
  • Manual Reset: Provides an option for manual reset using the MR pin.
  • Precision Monitoring: Offers accurate voltage monitoring with selectable threshold options.

Advantages

  • Low Power Consumption: Consumes only 1µA of quiescent current, making it suitable for battery-powered applications.
  • Small Package Size: Comes in a compact SOT23-8 package, saving board space.
  • Wide Supply Voltage Range: Operates from 1.6V to 5.5V, allowing compatibility with various power supply voltages.
  • Multiple Threshold Options: Provides flexibility by offering a range of threshold voltage options.

Disadvantages

  • Limited Reset Timeout Period: The reset timeout period is fixed at 140ms, which may not be suitable for all applications requiring longer timeouts.
  • Noisy Environments: May be susceptible to false triggering in noisy environments due to voltage fluctuations.

Working Principles

The MAX6367PKA29/V+T operates by continuously monitoring the input voltage using an internal voltage comparator. The selected threshold voltage determines the level at which the monitored voltage triggers a reset signal. When the input voltage falls below the threshold voltage, the reset output is activated. The reset remains active until the input voltage rises above the threshold voltage or a manual reset is triggered through the MR pin.

Detailed Application Field Plans

  • Battery-Powered Devices: Used to monitor battery voltage and initiate a reset when the voltage drops below a certain level.
  • Microcontroller Systems: Ensures proper system initialization by generating a reset signal during power-up or voltage fluctuations.
  • Industrial Control Systems: Provides voltage monitoring and reset functionality for critical control systems to maintain system integrity.
