Detailed Pin Configuration

The MAX6385XS16D5-T has a total of 5 pins:

1. GND: Ground connection
2. VCC: Supply voltage input
3. TH: Threshold voltage adjustment pin
4. RESET: Digital output indicating voltage level
5. MR: Manual reset input

Functional Features

• Monitors the voltage level at the TH pin and compares it with the internally set threshold voltage.
• When the voltage at the TH pin falls below the threshold, the RESET pin goes low, indicating a voltage fault condition.
• The threshold voltage can be adjusted using an external resistor divider connected to the TH pin.
• Provides a manual reset option through the MR pin.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide supply voltage range allows for flexibility in different power supply configurations.
• Adjustable threshold voltage enables customization for specific voltage monitoring requirements.

Disadvantages

• Limited number of threshold voltage options available in 100mV steps.
• SOT23-5 package may not be suitable for applications with space constraints.

Working Principles

The MAX6385XS16D5-T operates by comparing the voltage at the TH pin with the internally set threshold voltage. When the voltage at the TH pin falls below the threshold, the RESET pin goes low, indicating a voltage fault condition. The threshold voltage can be adjusted using an external resistor divider connected to the TH pin. Additionally, the MR pin allows for manual reset functionality.
