ZHCSHR6A March 2018 – January 2024 UCC27511A
PRODUCTION DATA
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. The UCC27511A device offers 2 input pins, IN+ and IN–, both of which control the state of the output as listed in Table 6-3. 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 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.
