Detailed Pin Configuration

The MAX6454UT23S+T has the following pin configuration:

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

Functional Features

  • Monitors the supply voltage and asserts a reset signal when it falls below the threshold voltage.
  • Provides a stable reset signal during power-up and power-down sequences.
  • Offers a fixed reset timeout period to ensure proper system initialization.

Advantages

  • Low quiescent current enables power-efficient operation.
  • Wide supply voltage range allows compatibility with various systems.
  • Small package size (SOT-23) facilitates space-constrained designs.
  • Accurate voltage monitoring enhances system reliability.
