1. VCC: Power supply input pin
2. GND: Ground pin
3. RESET: Output pin for reset signal

Functional Features

• Monitors the power supply voltage and generates a reset signal when the voltage falls below the set threshold.
• The reset signal remains active until the power supply voltage rises above the threshold and the reset timeout period elapses.
• The reset threshold voltage can be adjusted using an external resistor divider network.
• Provides a manual reset input for immediate system reset.
• Low quiescent current consumption makes it suitable for battery-powered applications.

Advantages

• Precise voltage monitoring helps prevent system malfunctions due to low voltage conditions.
• Adjustable reset threshold allows flexibility in setting the desired voltage level for triggering a reset.
• Small package size enables space-saving designs in compact electronic systems.
• Low quiescent current consumption prolongs battery life in portable devices.

Disadvantages

• The fixed or adjustable reset timeout period may not be suitable for all applications, requiring additional external components for customization.
• Limited number of pins restricts the availability of additional features or functionalities.

Working Principles

The MAX6383LT22D3+T operates by continuously monitoring the power supply voltage using an internal voltage reference and comparator. When the voltage falls below the set threshold, the reset output is activated, indicating a low voltage condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses. The reset threshold can be adjusted using an external resistor divider network.
