Detailed Pin Configuration

The MAX6313UK26D3-T has three pins:

1. GND: Ground connection.
2. RESET: Output pin that provides the reset signal to the system.
3. VCC: Power supply input.

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage drops below the set threshold.
• Reset timeout period can be adjusted according to system requirements.
• Low quiescent current consumption.
• Built-in glitch immunity to prevent false resets.
• Wide operating voltage range allows compatibility with various systems.

Advantages

• Ensures reliable system initialization by providing a power-on reset.
• Protects sensitive components from improper voltage levels.
• Adjustable reset timeout period allows flexibility in system design.
• Small package size (SOT23-3) saves board space.
• Low power consumption extends battery life in portable applications.

Disadvantages

• Limited threshold voltage options may not cover all voltage requirements.
• Lack of built-in hysteresis may result in oscillations near the threshold voltage.
• Sensitive to noise and voltage spikes in the power supply.

Working Principles

The MAX6313UK26D3-T operates by comparing the input voltage (VCC) with a reference voltage. When VCC falls below the set threshold voltage, the internal circuit generates a reset signal on the RESET pin. The reset signal remains active until VCC rises above the threshold voltage and the adjustable timeout period elapses.
