  • Use: Voltage Monitor
  • Characteristics: Low-power, precision voltage monitoring
  • Package: SOT23-6
  • Essence: Monitors the voltage level of a power supply and provides an output signal when it falls below or exceeds a certain threshold.
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Threshold Voltage Options: 1.8V, 2.5V, 3.0V, 3.3V, 4.63V
  • Quiescent Current: 1µA (typical)
  • Operating Temperature Range: -40°C to +125°C

Detailed Pin Configuration

The MAX6719UTSGD3+T has six pins arranged as follows: 1. GND: Ground connection 2. IN: Input voltage to be monitored 3. SET: Output pin for setting the threshold voltage 4. RESET: Active-low reset output 5. VCC: Power supply input 6. NC: No connection

Functional Features

  • Precision Monitoring: The MAX6719UTSGD3+T accurately monitors the input voltage with a low tolerance.
  • Adjustable Threshold: The threshold voltage can be set using an external resistor divider connected to the SET pin.
  • Reset Output: The active-low RESET pin provides an output signal when the monitored voltage falls below the threshold.
  • Low Power Consumption: With a quiescent current of only 1µA, the device minimizes power consumption.

Advantages and Disadvantages

Working Principles

The MAX6719UTSGD3+T operates by comparing the input voltage with a reference voltage set by the external resistor divider connected to the SET pin. When the input voltage falls below the threshold, the active-low RESET pin is asserted, indicating a power failure or an out-of-range condition. The device continuously monitors the input voltage and provides a reliable output signal.
