Working Principles

The TLV3491AID 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 IN-, the output (OUT) goes low, and when the voltage at IN+ is lower than IN-, the output goes high. The open drain output configuration allows the user to connect external pull-up resistors for different output configurations.
