MAX825TEUK+T

Product Overview

  • Category: Integrated Circuit (IC)
  • Use: Voltage Supervisor
  • Characteristics: Low-power, precision voltage monitoring
  • Package: SOT23-5
  • Essence: Monitors the power supply voltage and provides a reset signal when it falls below a certain threshold.
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.6V to 6.0V
  • Reset Threshold Options: 2.5V, 3.0V, 3.3V, 3.6V
  • Reset Timeout Options: 140ms, 280ms, 560ms, 1120ms
  • Operating Temperature Range: -40°C to +85°C
  • Quiescent Current: 3µA (typical)

Pin Configuration

The MAX825TEUK+T has a total of 5 pins:

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

Functional Features

  • Monitors the power supply voltage continuously
  • Generates a reset signal when the voltage falls below the set threshold
  • Provides manual reset capability through the MR pin
  • Low quiescent current for power-efficient operation
  • Wide operating voltage range for versatility

Advantages and Disadvantages
