```

| | --|----|-- |____| ```

Pin Description: 1. GND: Ground connection 2. RESET: Active-low reset output 3. MR: Manual reset input 4. TH: Threshold voltage selection input 5. VCC: Positive power supply input

Functional Features

  • Precision voltage monitoring: The MAX6752KA32/V+T accurately monitors the power supply voltage and provides a reset signal when it falls below a specified threshold.
  • Low-power operation: With a quiescent current of only 1µA, this IC minimizes power consumption in battery-powered applications.
  • Reset timeout period: The device ensures that the reset signal remains active for a minimum duration of 140ms after the power supply voltage rises above the threshold.

Advantages and Disadvantages

Advantages: - High accuracy voltage monitoring - Low power consumption - Small package size for space-constrained designs

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

Working Principles

The MAX6752KA32/V+T operates by comparing the power supply voltage with a user-selectable threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted low. The reset signal remains active for a minimum duration of 140ms after the supply voltage rises above the threshold.

Detailed Application Field Plans

The MAX6752KA32/V+T finds applications in various fields, including:

  1. Battery-powered devices: Ensures proper operation and prevents data loss by monitoring the battery voltage and initiating a reset when it falls below a critical level.
  2. Industrial control systems: Provides reliable supervision of power supply voltages in industrial automation equipment, preventing malfunctions and ensuring safe operation.
  3. Automotive electronics: Monitors the vehicle's power supply to protect sensitive electronic components from voltage fluctuations and ensure stable performance.
