  3. MR: Manual Reset Input
  4. RESET: Reset Output
  5. TH: Threshold Voltage Selection
  6. CT: Capacitor Connection for Reset Timeout
  7. GND: Ground
  8. VCC: Supply Voltage Input

Functional Features

  • Accurate monitoring of power supply voltages
  • Generates a reset signal when the voltage falls below the threshold
  • Adjustable reset timeout period for flexibility in system design
  • Manual reset input for immediate system reset
  • Low-power consumption for energy-efficient applications

Advantages

  • Precise voltage monitoring ensures reliable system operation
  • Adjustable reset timeout allows customization based on specific requirements
  • Manual reset input provides control over system reset
  • Low-power consumption extends battery life in portable devices
  • Small package size enables space-saving PCB designs

Disadvantages
