Detailed Pin Configuration

  1. GND: Ground connection
  2. RESET: Active-low reset output
  3. TH: Threshold input for setting voltage level
  4. MR: Manual reset input
  5. VCC: Positive supply voltage input

Functional Features

  • Monitors the supply voltage and generates a reset signal when it falls below the threshold voltage.
  • Adjustable threshold voltage allows customization for different applications.
  • Manual reset input provides external control over the reset function.
  • Low quiescent current ensures minimal power consumption.

Advantages

  • Wide supply voltage range enables compatibility with various systems.
  • Precision voltage monitoring enhances system reliability.
  • Adjustable thresholds offer flexibility in voltage level detection.
  • Low-power operation prolongs battery life in portable devices.
  • Small package size saves board space.

Disadvantages

  • Limited threshold voltage options may not cover all specific requirements.
  • Lack of built-in hysteresis may result in potential oscillations near the threshold voltage.

Working Principles

The MAX6425UK20+T is a voltage supervisor IC that continuously monitors the supply voltage. It compares the voltage level with the threshold set by the TH pin. When the supply voltage drops below the threshold, the RESET pin is asserted low, indicating a reset condition. The manual reset input (MR) allows an external signal to override the monitoring function and assert the reset signal.

Detailed Application Field Plans

  • Battery-powered devices: Ensures proper operation and prevents damage due to low battery voltage.
  • Microcontroller systems: Provides reliable reset signals during power-up and brownout conditions.
  • Industrial control systems: Monitors critical voltage levels to prevent system failures.
  • Automotive electronics: Protects sensitive components from voltage fluctuations.
