Detailed Pin Configuration

The MAX16091UK44DIB+T features a 4-bump WLP package with the following pin configuration:

  1. VDD: Supply voltage input
  2. GND: Ground reference
  3. RESET#: Active-low reset output
  4. MR#: Manual reset input

Functional Features

  • Precise voltage monitoring: The MAX16091UK44DIB+T accurately monitors the supply voltage and generates a reset signal when it falls below a specified threshold.
  • Low-power operation: With a quiescent current of only 1.5µA, the device minimizes power consumption in battery-powered applications.
  • Reset timeout period: The reset signal remains active for a fixed duration (140ms) after the supply voltage rises above the threshold, ensuring proper system initialization.

Advantages and Disadvantages

Advantages: - High accuracy voltage monitoring - Low power consumption - Small form factor package - Wide supply voltage range

Disadvantages: - Limited threshold voltage options - Manual reset input may require additional external components for implementation

Working Principles

The MAX16091UK44DIB+T operates by continuously monitoring the supply voltage using an internal voltage reference and comparator. When the voltage falls below the programmed threshold, the reset output is asserted low, indicating a system fault or power loss. The reset signal remains active for the specified timeout period after the voltage rises above the threshold.
