  2. GND: Ground reference pin
  3. RESET: Active-low reset output pin
  4. MR: Manual reset input pin
  5. TH: Threshold voltage selection pin

Functional Features

  • Accurate monitoring of power supply voltages
  • Generates a reset signal when voltage falls below the specified threshold
  • Adjustable or fixed reset timeout period options
  • Manual reset capability for system control
  • Low quiescent current for power efficiency

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures reliable system operation - Flexible reset timeout options cater to various application requirements - Low-power consumption extends battery life in portable devices - Small package size allows for space-efficient designs

Disadvantages: - Limited threshold voltage options may not cover all voltage monitoring needs - Manual reset input may require additional external components for proper functionality

Working Principles

The MAX6388XS42D7-T operates by continuously monitoring the power supply voltage connected to the VCC pin. It compares the voltage against a pre-set threshold value, which can be selected using the TH pin. When the voltage falls below the threshold, the RESET pin is driven low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin.
