• Small Package Size: The SOT-23-3 package allows for space-efficient integration into compact electronic designs.
• RoHS Compliant: This product meets the Restriction of Hazardous Substances directive, ensuring environmental friendliness.

Disadvantages

• Single Voltage Range: The MIC6315-42D3UY-TR is designed to operate within a specific voltage range (1.8V to 5.5V), limiting its compatibility with wider voltage ranges.

Working Principles

The MIC6315-42D3UY-TR utilizes a voltage comparator to continuously monitor the input voltage. When the voltage falls below the reset threshold of 4.2V, the comparator triggers the active-low reset output, indicating a reset condition. This feature ensures that the connected circuitry remains in a safe state during undervoltage conditions.
