6.3.2 Enable Function

The enable (EN) pin of the UCC5710xW device also has TTL compatible input thresholds with wide hysteresis. The typical turnon threshold is 2.2V and the typical turnoff threshold is 1.2V with typical hysteresis of 1V. The enable (EN) pin of the UCC5710xW has an internal pullup resistor to an internal reference voltage. Thus, leaving the enable pin floating turns on the driver and allows it to send output signals properly. If desired, the enable pin can also be driven by low-voltage logic to enable and disable the driver. There is minimum delay from the enable block to the output for fast system response time. Similar to the input pins, the enable pin can also handle significant negative voltage and therefore provides system robustness. The enable pin can withstand a wide range of slew rates such as 1V/ns to 1V/ms. The enable signal is independent of VDD voltage and stable across the full operating temperature range.
