MAX6388XS22D2-T

Product Overview

  • Category: Integrated Circuit (IC)
  • Use: Voltage Monitor
  • Characteristics: Low-power, Precision, Adjustable Threshold
  • Package: SOT23-5
  • Essence: Monitors voltage levels and provides a digital output signal based on the threshold set by the user.
  • Packaging/Quantity: Tape & Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Threshold Voltage Options: 2.2V
  • Operating Temperature Range: -40°C to +85°C
  • Quiescent Current: 3µA (typical)

Pin Configuration

The MAX6388XS22D2-T has a total of 5 pins:

  1. GND: Ground connection
  2. VCC: Supply voltage input
  3. TH: Threshold voltage selection pin
  4. RESET: Digital output indicating voltage level
  5. MR: Manual reset input

Functional Features

  • Monitors the voltage level at the TH pin and compares it with the threshold voltage set by the user.
  • When the voltage at the TH pin drops below the threshold, the RESET pin goes low, indicating a voltage fault condition.
  • The MR pin allows for manual resetting of the device.

Advantages and Disadvantages

Advantages: - Low-power consumption makes it suitable for battery-powered applications. - Adjustable threshold voltage provides flexibility in monitoring different voltage levels. - Small package size enables space-saving designs.

Disadvantages: - Limited threshold voltage options may not cover all desired voltage levels. - Lack of built-in hysteresis may result in unstable output when the input voltage is near the threshold.

Working Principles

The MAX6388XS22D2-T operates by comparing the voltage at the TH pin with the threshold voltage set by the user. When the TH voltage drops below the threshold, the RESET pin goes low, indicating a voltage fault condition. The MR pin allows for manual resetting of the device.
