UCC27714: Driver IC with 800V+ , 4A double channel

Tanvi Mahajan

Part Number: UCC27714
Other Parts Discussed in Thread: UCC21520-Q1

Hello

I need a driver IC for DC/DC converter with input handling up to 800V/900V or more; 4A current is required for high and low side with automative grade. I have got UCC27714 matching to my requirement with highest voltage available. Can you suggest me other part number available according to my requirement.?

Thanks in advance.

Hi Tanvi,

I am an applications engineer supporting high voltage gate drivers. TI does not currently have a dedicated half-bridge driver with 900V input handling. I recommend taking a look at UCC21520-Q1: This part has two independent channels, 4A source/6A sink, automotive rating, and a working voltage of 1500Vdc between channels.

Hello Derek

Thanks a lot for your help. I just want to confirm that this driver IC can handle my 600V DC voltage at the input side of high side MOSFET. As the 1500V DC voltage is specified at the switching node. According to me , it will work just asking so that I am not missing any minute detail.

Thanks in advance.

Hi Tanvi,

You can definitely use UCC21520-Q1 in a 600V high-side/low-side configuration. The application and implementation section of the datasheet uses an 800V DC bus in a half-bridge configuration, so 600V is definitely within the allowable operating range. The circuits of the output channels are isolated from each other and from the control side, and all isolation ratings are much greater than 600V.
