| | --|----|-- |____| ```

1. VCC: Power Supply Input
2. GND: Ground
3. RESET: Active-Low Reset Output
4. MR: Manual Reset Input

Functional Features

• Monitors the voltage level continuously
• Generates a reset signal when the voltage drops below the set threshold
• Provides a debounced active-low reset output
• Offers a manual reset input for external control

Advantages

• Small package size allows for space-saving designs
• Wide supply voltage range enables compatibility with various systems
• Multiple threshold voltage options provide flexibility for different applications
• Low power consumption
• Reliable reset signal generation ensures system stability

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer delays
• SOT-143 package may have limitations in terms of heat dissipation

Working Principles

The MAX6388XS44D4-T operates by continuously monitoring the voltage level of the power supply. When the voltage falls below the set threshold, it generates an active-low reset signal. This signal remains active until the voltage rises above the threshold and a timeout period elapses.

The device also includes a manual reset input that allows external control over the reset function. When the MR pin is pulled low, the reset output is activated regardless of the voltage level.

Detailed Application Field Plans

The MAX6388XS44D4-T is commonly used in various electronic systems where a reliable power-on reset is required. Some application fields include:

1. Microprocessors and microcontrollers
2. Digital signal processors
3. Embedded systems
4. Communication devices
5. Industrial control systems
6. Automotive electronics
