7.2.1.2.5 Enable and Disable Function

Certain applications demand independent control of the output state of the driver without involving the input PWM signal. A pin which offers an enable and disable function achieves this requirement. For these applications, the UCC27614-Q1 D and DGN are suitable as they feature an input pin (IN) and an Enable pin (EN). Both of these pins are independent of each other and are also independent of VDD.

Other applications require multiple inputs. For such applications the UCC27614-Q1 DSG is suitable. The UCC27614-Q1DSG features an IN+ and IN– pin, both of which control the state of the output as listed in the Device Functional Modes truth table. 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+ is the unused pin), or GND (in case IN– is unused pin) in order to ensure it does not affect the output status.
