```

---

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

1. Pin 1: GND (Ground)
2. Pin 2: RESET (Reset Output)
3. Pin 3: MR (Manual Reset Input)
4. Pin 4: VCC (Supply Voltage)
5. Pin 5: N/C (No Connection)

Functional Features

• Monitors the supply voltage and provides a reset signal when it falls below a specified threshold.
• Offers a manual reset input for immediate system restart.
• Low quiescent current ensures minimal power consumption.
• Provides a stable reset output during power-up and power-down sequences.

Advantages and Disadvantages

Advantages: - High accuracy in monitoring voltage levels. - Low power consumption extends battery life in portable devices. - Small package size allows for space-efficient designs.

Disadvantages: - Limited threshold voltage options may not suit all applications. - Reset timeout period may not be adjustable, limiting flexibility in certain scenarios.

Working Principles

The MAX6752KA29+TG51 operates by continuously monitoring the supply voltage. When the voltage falls below the preset threshold (2.9V), the IC asserts the reset output pin, signaling a system reset. The reset signal remains active until the supply voltage rises above the threshold and stabilizes for the specified reset timeout period (140ms).

Detailed Application Field Plans

The MAX6752KA29+TG51 is widely used in various electronic systems where reliable voltage monitoring is critical. Some application fields include:

1. Power Management: Ensuring stable power supply in battery-powered devices such as smartphones, tablets, and wearables.
2. Industrial Control Systems: Monitoring voltage levels in control panels, PLCs, and motor drives to prevent malfunctions and ensure safe operation.
3. Automotive Electronics: Voltage supervision in automotive ECUs, infotainment systems, and safety modules to enhance reliability and prevent system failures.
4. Medical Devices: Maintaining proper voltage levels in medical equipment to guarantee accurate measurements and patient safety.

Detailed and Complete Alternative Models

1. MAX6753KA29+TG51: Similar to MAX6752KA29+TG51 but with a different threshold voltage option (2.9V).
2. MAX6754KA29+TG51: Voltage supervisor with a higher threshold voltage option (3.0V) for specific applications.
