---

| | --| VCC GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Reset Output (RESET OUT) --| MR |-- Pin 3: Manual Reset Input (MR) --| TH |-- Pin 4: Threshold Selection (TH) --| TR |-- Pin 5: Timeout Period Selection (TR) --| VCC |-- Pin 6: Power Supply (VCC) |___________| ```

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage falls below the selected threshold.
• Provides an adjustable reset timeout period.
• Offers a manual reset input for external control.

Advantages and Disadvantages

Advantages: - Low quiescent current consumption. - Wide supply voltage range. - Adjustable reset threshold and timeout period. - Small package size for space-constrained applications.

Disadvantages: - Limited number of available threshold options. - Manual reset input may require additional external components for proper functionality.

Working Principles

The MAX6756UKTD0/V+T operates by continuously monitoring the power supply voltage connected to its VCC pin. When the voltage falls below the selected threshold, the IC generates a reset signal on the RESET OUT pin. The reset signal remains active until the voltage rises above the threshold or a timeout period elapses. The reset timeout period can be adjusted using the TR pin. Additionally, an external manual reset input (MR) allows for manual control of the reset signal.

Detailed Application Field Plans

The MAX6756UKTD0/V+T is commonly used in various applications where reliable voltage monitoring and reset generation are required. Some potential application fields include:

1. Microcontroller Systems: Ensuring proper system initialization and preventing erratic behavior during power-up or voltage fluctuations.
2. Industrial Control Systems: Providing reliable reset signals to critical components such as PLCs, motor drives, and sensors.
3. Battery-Powered Devices: Monitoring battery voltage to prevent damage due to over-discharge and ensure safe operation.
4. Automotive Electronics: Resetting microcontrollers and other electronic modules during power cycling or abnormal voltage conditions.
