7.3.3 Enable Function

The enable (EN) pin of the UCC27532-Q1 device has an internal pullup resistor to an internal reference voltage. Therefore, leaving the EN pin floating turns on the driver and allows it to send output signals properly. If desired, the EN pin can also be driven by low-voltage logic to enable and disable the driver.
