Detailed Pin Configuration

The MAX6314US28D4+TG05 has a total of 5 pins: 1. GND: Ground connection 2. MR: Manual Reset input pin 3. RESET: Active-low reset output 4. VCC: Positive power supply input 5. TH: Threshold voltage selection pin

Functional Features

• Voltage Monitoring: The MAX6314US28D4+TG05 continuously monitors the power supply voltage and compares it with the selected threshold voltage.
• Reset Generation: When the power supply voltage falls below the threshold voltage, the reset output is asserted low, indicating a system reset condition.
• Manual Reset: The manual reset input allows for an external reset signal to override the internal monitoring circuitry.
• Adjustable Reset Timeout: The timeout period for the reset signal can be adjusted using an external capacitor.

Advantages and Disadvantages

Advantages: - Low-power consumption makes it suitable for battery-powered applications. - Wide operating voltage range allows for compatibility with various power supply voltages. - Small package size enables space-saving designs.

Disadvantages: - Limited threshold voltage options may not cover all voltage requirements. - Fixed reset timeout periods may not be optimal for all applications.

Working Principles

The MAX6314US28D4+TG05 operates by continuously monitoring the power supply voltage through the TH pin. When the voltage falls below the selected threshold voltage, the internal circuitry generates a reset signal on the RESET pin. This reset signal remains active until the power supply voltage rises above the threshold voltage or a manual reset signal is applied to the MR pin. The reset timeout period can be adjusted using an external capacitor connected to the CT pin.

Detailed Application Field Plans

The MAX6314US28D4+TG05 is commonly used in various electronic devices that require reliable power supply monitoring and reset functionality. Some application fields include: - Microcontrollers and microprocessors - Embedded systems - Industrial control systems - Communication equipment - Consumer electronics
