Detailed Pin Configuration

The MAX6412UK18+T IC has a total of 5 pins: 1. GND: Ground connection 2. MR: Manual Reset input pin 3. RESET: Active-low Reset output pin 4. VCC: Positive supply voltage input 5. TH: Threshold voltage selection pin

Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the threshold voltage.
• Provides an adjustable reset timeout period to ensure proper system initialization.
• Offers a manual reset input for immediate system reset.
• Low quiescent current consumption makes it suitable for battery-powered applications.

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Adjustable reset timeout period offers flexibility in system design.
• Small package size enables space-saving on PCBs.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited threshold voltage options may not cater to all voltage requirements.
• Lack of built-in hysteresis may result in false triggering in noisy environments.

Working Principles

The MAX6412UK18+T operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the selected threshold voltage, the RESET pin is asserted low, indicating a reset condition. The reset signal remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses.

Detailed Application Field Plans

• Microcontroller-based systems requiring reliable power-on reset functionality.
• Battery-powered devices where low quiescent current consumption is crucial.
• Embedded systems that need adjustable reset timeout periods for proper initialization.
