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

• Pin 1: GND (Ground)
• Pin 2: MR (Manual Reset Input)
• Pin 3: VCC (Power Supply)
• Pin 4: RESET (Reset Output)

Functional Features

• Monitors the power supply voltage continuously
• Generates a reset signal when the voltage falls below the programmed threshold
• Provides a manual reset input for immediate system reset
• Fixed reset timeout period ensures proper system recovery

Advantages

• Wide supply voltage range allows compatibility with various systems
• Adjustable threshold voltage provides flexibility for different applications
• Low quiescent current minimizes power consumption
• Small form factor package enables space-saving designs

Disadvantages

• Fixed reset timeout period may not be suitable for all applications requiring longer or shorter timeouts
• Limited pin configuration options may restrict certain system designs

Working Principles

The MAX6385XS23D4-T operates by comparing the power supply voltage with the programmed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure. The reset signal remains active for the fixed timeout period, allowing the system to recover. Additionally, the manual reset input can be used to force an immediate system reset.

Application Field Plans

The MAX6385XS23D4-T finds applications in various fields, including:

1. Battery-powered devices: Ensures proper operation and prevents data loss during low battery conditions.
2. Industrial control systems: Monitors power supply integrity and resets the system in case of voltage fluctuations.
3. Automotive electronics: Protects sensitive components from voltage dips and spikes, ensuring reliable performance.
4. Medical equipment: Provides a fail-safe mechanism to prevent malfunctions due to power supply issues.
5. Home automation: Enables safe and reliable operation of smart home devices by monitoring power supply stability.
