• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6387XS31D3+T has three pins:

1. GND: Ground connection
2. RESET: Output pin for reset signal
3. VCC: Power supply input

Functional Features

• Monitors the voltage level of the power supply continuously.
• Generates a reset signal when the voltage falls below the programmed threshold.
• Provides an adjustable reset timeout period.
• Low-power consumption.

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Precise voltage monitoring ensures reliable operation.
• Adjustable reset timeout period offers flexibility in system design.
• Small package size (SOT23-3) saves board space.
• Low-power consumption extends battery life in portable applications.

Disadvantages

• Limited number of threshold voltage options may not suit all applications.
• Lack of built-in hysteresis may result in multiple reset signals during voltage fluctuations.

Working Principles

The MAX6387XS31D3+T operates by comparing the supply voltage with a programmed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated. The reset signal remains active until the supply voltage rises above the threshold or the adjustable timeout period elapses.

Detailed Application Field Plans

• Battery-powered devices: Provides reliable reset functionality to prevent erratic behavior when the battery voltage drops.
• Microcontroller systems: Ensures proper system initialization by generating a reset signal during power-up and voltage fluctuations.
• Industrial control systems: Monitors power supply integrity and initiates system reset if necessary.
• Automotive electronics: Protects sensitive components from voltage dips and spikes by triggering a reset when needed.
