Pin Configuration

The MAX6314US30D4-T has four pins in a SOT-143 package:

  1. GND: Ground pin
  2. TRIP: Output pin that goes low when the monitored voltage falls below the threshold
  3. TH: Threshold adjustment pin
  4. VCC: Power supply pin

Functional Features

  • Low-power consumption makes it suitable for battery-powered applications
  • Adjustable threshold allows customization for different voltage levels
  • Precision monitoring ensures accurate detection of voltage drops
  • Open-drain output can be easily interfaced with other devices

Advantages

  • Wide supply voltage range enables compatibility with various systems
