Enable

The UCC2742x-Q1 devices provide dual enable inputs for improved control of each driver channel operation. The inputs incorporate logic-compatible thresholds with hysteresis. They are internally pulled up to VDD with 100-kΩ resistor for active-high operation. When ENBA and ENBB are driven high, the drivers are enabled; when ENBA and ENBB are low, the drivers are disabled. The default state of the enable pin is to enable the driver and, therefore, can be left open for standard operation. The output states when the drivers are disabled is low, regardless of the input state. See Table 7-1 for operation using enable logic.

Enable inputs are compatible with both logic signals and slowly-changing analog signals. They can be directly driven, or a power-up delay can be programmed with a capacitor between ENBA/ENBB and GND. ENBA and ENBB control input A and input B, respectively.
