---

| | --| VCC GND |-- Pin 1: Ground (GND) --| MR RST |-- Pin 2: Reset Output (RST) --| TH VCC |-- Pin 3: Supply Voltage (VCC) --| GND GND |-- Pin 4: Ground (GND) --| TR GND |-- Pin 5: Threshold Input (TR) --| RESET GND |-- Pin 6: Ground (GND) |___________| ```

Functional Features

• Monitors the power supply voltage and generates a reset signal when the voltage drops below the set threshold.
• Adjustable reset threshold allows customization for different system requirements.
• Fixed reset timeout period ensures a reliable reset signal is generated even during power supply glitches.
• Low quiescent current minimizes power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring helps prevent system malfunctions due to low voltage conditions. - Adjustable reset threshold provides flexibility for various applications. - Small package size enables space-saving designs in compact electronic systems. - Low-power operation extends battery life in portable devices.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications requiring longer or shorter timeouts. - Limited supply voltage range may restrict compatibility with certain systems.

Working Principles

The MAX6388XS46D2-T operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the set threshold, the internal comparator triggers a reset signal on the RST pin. The reset signal remains active for the fixed timeout period, ensuring proper system initialization after a power supply glitch or voltage drop.
