  • Reset Threshold Voltage Options: 2.93V, 3.08V, 4.63V, 4.38V (typical)

Detailed Pin Configuration

The STM6822YWY6F IC has the following pin configuration:

  1. VDD: Supply voltage input
  2. GND: Ground reference
  3. MR: Manual reset input
  4. WDI: Watchdog timer input
  5. RESET: Reset output
  6. NC: No connection

Functional Features

  • Voltage supervision: Monitors the supply voltage and asserts a reset signal if it falls below a specified threshold.
  • Watchdog timer: Detects system malfunctions by periodically receiving a signal from an external source. If the signal is not received within the timeout period, a reset signal is generated.
  • Manual reset: Allows for manual assertion of the reset signal.
  • Power-on reset delay: Provides a fixed delay after the supply voltage rises above the reset threshold before releasing the reset signal.

Advantages and Disadvantages

Advantages: - High efficiency power management solution - Low power consumption - Small form factor package - Wide supply voltage range

Disadvantages: - Limited number of reset threshold voltage options - No adjustable watchdog timer timeout period

Working Principles

The STM6822YWY6F is designed to ensure reliable operation of electronic systems by monitoring the supply voltage and detecting system malfunctions. It operates by comparing the supply voltage with a preset threshold. If the voltage falls below the threshold, the reset output is asserted, indicating that the system should be reset.

Additionally, the IC includes a watchdog timer that requires an external signal to be periodically received within a specified timeout period. If the signal is not received, the reset output is generated, indicating a potential system malfunction.

Detailed Application Field Plans

The STM6822YWY6F is commonly used in various applications where power management and system reliability are critical. Some specific application fields include:

  1. Battery-powered devices: Ensures proper functioning and prevents damage due to low battery voltage.
  2. Industrial control systems: Provides supervision and resets capabilities for critical components in industrial automation.
  3. Automotive electronics: Monitors the vehicle's electrical system and triggers a reset if necessary.
  4. Medical equipment: Ensures reliable operation and patient safety by monitoring power supply integrity.
  5. Home automation: Enhances the stability and reliability of smart home devices.
