Working Principles

The MCP6544T-I/ST is a voltage comparator that compares the voltage at the IN+ pin with the voltage at the IN- pin. When the voltage at IN+ is higher than the voltage at IN-, the output (OUT) goes high. Conversely, when the voltage at IN- is higher, the output goes low. The comparator operates within the specified supply voltage range and provides a fast response time.
