Detailed Pin Configuration

The MAX6314US26D1/GG8 has a total of five pins:

1. VCC: Power supply input pin
2. GND: Ground reference pin
3. MR: Manual reset input pin
4. RESET: Active-low reset output pin
5. TH: Threshold voltage selection pin

Functional Features

• Monitors the power supply voltage and asserts the reset output when the voltage drops below the threshold.
• Provides a manual reset input for immediate system reset.
• Offers a fixed delay period after the voltage rises above the threshold before deasserting the reset output.
• Low quiescent current consumption makes it suitable for battery-powered applications.
• Small package size allows for space-constrained designs.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures reliable system operation. - Manual reset input provides flexibility in system control. - Low-power consumption extends battery life. - Small package size enables compact designs.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications requiring different delay durations. - Limited threshold voltage options may restrict compatibility with certain power supply voltages.

Working Principles

The MAX6314US26D1/GG8 operates by continuously monitoring the power supply voltage through the TH pin. When the voltage drops below the threshold, the reset output is asserted, indicating a low-voltage condition. The manual reset input (MR) allows the user to manually trigger a system reset. After the voltage rises above the threshold, the reset output remains asserted for a fixed 140ms delay period before deasserting.

Detailed Application Field Plans

The MAX6314US26D1/GG8 is commonly used in various electronic systems where reliable voltage monitoring and manual reset functionality are required. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial automation equipment
4. Power management systems
5. Portable devices
