UCC21330-Q1: Reference design for driving high side FET's in BMS

Part Number: UCC21330-Q1
Other Parts Discussed in Thread: UCC21540-Q1, UCC21222-Q1, UCC21520-Q1, , UCC21530-Q1

Tool/software:

Can someone please share the reference design for driving high side MOSFET's with Isolated gate drivers in BMS application.

  • Hi Bhuvaneswar,

    We do not have an exact reference design that meets your request. However, the TIDA-00159 reference design shows one of our dual channel isolated gate drivers in a simple compact half-bridge configuration.

    The TIDA-01605 reference design also is a good reference for a half-bridge configuration that shows driving high side FETs.

    Although we do not currently have any reference designs for our new devices such as UCC21330-Q1, you can take a look through the rest of our isolated dual channel gate driver portfolio (UCC21520-Q1, UCC21530-Q1, UCC21540-Q1, UCC21222-Q1, UCC21220-Q1, etc..) to find reference designs that may be helpful in your design. These should all follow a similar application design and will be mostly applicable to UCC21330-Q1. 

    Hope this is helpful. Feel free to ask any additional questions below.

    Regards,

  • Hi Hiroki,

    Thanks for sharing the reference designs. Are there any considerations that I need to consider for driving high side MOSFET's in battery applications compared to the reference design of simple compact half bridge configuration.

  • Hi Bhuvaneswar,

    For simple standard drivers such as UCC21330-Q1, the gate driver surrounding circuitry should be very similar. If your application is for driving only high-side MOSFETs, an isolated supply would be necessary to driver the high-side MOSFETs.

    Section 8 of the datasheet goes into details for the gate driver surrounding circuitry.

    Hope this answers your question!

    Regards,
