Detailed Pin Configuration

The MAX6388XS21D3-T features a compact SOT23-3 package with the following pin configuration:

  1. GND (Ground)
  2. RESET (Reset Output)
  3. VCC (Supply Voltage)

Functional Features

  • Monitors the supply voltage and generates a reset signal when it falls below the set threshold.
  • Adjustable reset threshold allows customization for different applications.
  • Fixed reset timeout period ensures proper system reset.
  • Low quiescent current minimizes power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring helps prevent system malfunctions. - Adjustable reset threshold provides flexibility for different voltage requirements. - Small package size saves board space. - Low quiescent current reduces power consumption.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications. - Limited supply voltage range (1.6V to 5.5V).

Working Principles

The MAX6388XS21D3-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the set threshold, the RESET pin is asserted low, generating a reset signal. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
