Detailed Pin Configuration

The MAX6833HXRD3+T features a 6-pin Thin DFN package with the following pin configuration:

  1. GND: Ground connection
  2. RESET: Active-low reset output
  3. MR: Manual reset input
  4. VCC: Positive power supply
  5. TH: Threshold selection input
  6. TO: Timeout period selection input

Functional Features

  • Voltage Monitoring: Monitors the power supply voltage and generates a reset signal when it falls below a specified threshold.
  • Watchdog Timer: Detects system malfunctions by periodically resetting the system if a specific event does not occur within a defined time frame.
  • Manual Reset: Allows an external signal to force a system reset.
  • Power-On Reset: Generates a reset pulse during power-up to ensure a controlled start-up of the system.

Advantages and Disadvantages

Advantages: - Low-power consumption - High accuracy in voltage monitoring - Small package size - Wide operating temperature range

Disadvantages: - Limited number of threshold and timeout options - Lack of built-in hysteresis

Working Principles

The MAX6833HXRD3+T operates by continuously monitoring the power supply voltage using an internal voltage reference and comparator. When the voltage drops below the selected threshold, the reset output is activated, signaling a system reset. The watchdog timer ensures that the system remains responsive by periodically resetting it if a specific event does not occur within the defined timeout period.

Detailed Application Field Plans

The MAX6833HXRD3+T is commonly used in various applications where reliable power supply monitoring and system reset generation are critical. Some potential application fields include:

  1. Microcontrollers: Ensures proper operation and prevents data corruption during power supply fluctuations.
