UCC27712-Q1: UCC27712-Q1

Part Number: UCC27712-Q1

Dear Sir/Madam,

 I am using Ucc27712-Q1 driver ic for driving my high and low side mosfet. Even after referring the Datasheet of the same i am unable to understand the turning off of High side mosfet.

Does low side mosfet places role in switching off of high side mosfet .If yes then How?

Thanks 

Akanksha

  • Hey Akanksha,

    Thank you for reaching out to TI with your question regarding the UCC27712-Q1.

    The high-side output stage of the gate driver has a pull down structure that pulls HO low to HS. This pull down structure is made up of a N-Channel MOSFET. This is discussed in Section 8.3.4 Output Stage in the datasheet and an example can be seen showing the low-side in Figure 32. This structure holds true for the high side and can be seen in the Functional Block Diagram in Figure 29.

    Let me know if you have any further questions.

    Thank you,

    William Moore
