UCC23513: H-Bridge Gate Driver.

Part Number: UCC23513
Other Parts Discussed in Thread: UCC27524A

I am not trained in electronics and require assistance in acquiring the correct high-side gate driver for an H-Bridge module which I'm using to switch polarities in electromagnets (by reversing currents of the order of 50A in the DC circuit from a 12V battery). 

The module is a Vincotech FZ074PA75SM-L625F08 using IGBTs rated for 75A; Collector-Emitter Saturation Voltage 15V, Gate-Emitter Threshold Voltage 4V.  

Someone at the AAC forum suggested using your UCC 23513 isolated gate driver, and I'm wondering if that is appropriate for this application; or whether another component or type of component would be better, such as a half-bridge driver.  The further problem in this situation is the need for a bootstrapping circuit.

    Hi, James,

    Indeed you are correct... We just happen to have an EVM that solves this problem!

    You would need two of these, one for each high-side switch, and two low-side drivers as well to complete your h-bridge. Something like the UCC27524A. This Tech Note describes how to configure an H-bridge. Good luck with your project!

    Thank you Don.. I'm supposing without having looked closely yet that this EVM would solve the problem of bootstrapping.  It certainly seems suitable as the high-side gate driver.  After I've studied things further, I'll no doubt go ahead and order some of these, as well as the low-side drivers you suggested.  Thanks again.  james.
