MAX6899AAZT+T

Product Overview

  • Category: Integrated Circuit
  • Use: Voltage Monitor and Reset Circuit
  • Characteristics: Low-power, precision voltage monitoring, reset generation
  • Package: SOT23-6
  • Essence: Monitors the voltage level of a power supply and generates a reset signal when the voltage falls below a certain threshold.
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Threshold Voltage Options: 2.5V, 3.0V, 3.3V, 5.0V
  • Reset Timeout Period: Adjustable from 1ms to 640ms
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6899AAZT+T has the following pin configuration:

  1. GND (Ground)
  2. MR (Manual Reset Input)
  3. VCC (Power Supply)
  4. RESET (Reset Output)
  5. TH (Threshold Voltage Selection)
  6. TR (Reset Timeout Period Selection)

Functional Features

  • Monitors the voltage level of the power supply continuously.
  • Generates a reset signal when the voltage falls below the selected threshold.
  • Provides an adjustable reset timeout period for precise timing control.
  • Supports manual reset input for immediate system reset.

Advantages and Disadvantages

Advantages: - Low-power consumption, suitable for battery-powered applications. - Precision voltage monitoring ensures reliable system operation. - Adjustable reset timeout period allows customization for specific requirements. - Small package size enables space-saving designs.

Disadvantages: - Limited threshold voltage options may not cover all application scenarios. - Manual reset input may require additional external components for proper implementation.

Working Principles

The MAX6899AAZT+T operates by continuously monitoring the voltage level of the power supply connected to its VCC pin. When the voltage falls below the selected threshold voltage (set using the TH pin), the device generates a reset signal on the RESET pin. The reset timeout period, determined by the TR pin, can be adjusted to control the duration of the reset signal.

In case an immediate system reset is required, the MR pin can be used for manual reset input. This pin overrides the voltage monitoring and generates an instant reset signal.

Detailed Application Field Plans

The MAX6899AAZT+T is commonly used in various applications where reliable voltage monitoring and reset generation are crucial. Some typical application fields include:

  1. Microcontrollers and Microprocessors: Ensures proper system initialization and prevents erratic behavior during power-up or brownout conditions.
  2. Industrial Control Systems: Provides reliable reset signals to ensure safe operation and prevent damage to equipment.
  3. Automotive Electronics: Monitors battery voltage and generates reset signals to protect critical systems during low-voltage conditions.
  4. Portable Devices: Enables graceful shutdown or restart when the battery voltage drops below a certain level.
  5. Power Management Systems: Facilitates efficient power management by monitoring supply voltages and initiating appropriate actions.

Detailed and Complete Alternative Models

  • MAX809: Voltage Monitor and Reset Circuit with fixed threshold voltage options.
  • MAX6710: Dual Voltage Monitor and Reset Circuit with adjustable threshold voltage options.
  • MAX638: Voltage Monitor and Reset Circuit with additional features like watchdog timer and power-fail detection.

These alternative models offer similar functionality but may have different specifications, package options, or additional features to suit specific application requirements.
