Detailed Pin Configuration

MIC1815-10UY-TR has three pins:

1. VDD: This pin is connected to the positive supply voltage.
2. GND: This pin is connected to the ground or negative supply voltage.
3. RESET: This pin outputs an active low signal when the voltage falls below the threshold.

Functional Features

• Monitors the voltage level and provides a reset signal when it falls below the threshold.
• Push-pull output ensures a strong and reliable reset signal.
• Low quiescent current allows for power-efficient operation.
• Wide supply voltage range makes it compatible with various electronic systems.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures reliable circuit operation.
• Small package size enables space-saving designs.
• Low quiescent current minimizes power consumption.
