9.2.1.2.5 Enable and Disable Function

Certain applications demand independent control of the output state of the driver without involving the input signal. A pin which offers an enable and disable function achieves this requirement. For these applications, the UCC27531, UCC27536, or UCC27537 are suitable as they feature an input pin (IN– for UCC27536) and an Enable pin.

Other applications require multiple inputs. Under those requirements, the UCC27533 or UCC27538 are suitable. The UCC27533 features an IN+ and IN– pin, both of which control the state of the output as listed in Table 3. Based on whether an inverting or non-inverting input signal is provided to the driver, the appropriate input pin can be selected as the primary input for controlling the gate driver. The other unused input pin can be conveniently used for the enable and disable functionality if needed. If the design does not require an enable function, the unused input pin can be tied to either the VDD pin (in case IN+ is the unused pin), or GND (in case IN– is unused pin) in order to ensure it does not affect the output status. The UCC27538 features two independent inputs IN1 and IN2. These contain the same functionality as the UCC27533, but instead both of these IN1 and IN2 pins are non-inverting.
