Part Number:BQ76200
Hello again;
Sanity check - client's current FET disconnect board has the N MOSFET's oriented with common sources. I need confirmation that I can control them with the 76200. I've Spiced a simple circuit (attached) and it appears to function as desired, by swapping the CHG and DSG signals. Am I missing something obvious, and/or do you not recommend this use case?
Note that the FET used in the sim's was used because it has very large Qg. My client's application will use 16 AUIRF7759 (8:2), 330nQ, 75V. I'll be testing the 76200 with a mach'd-up disconnect board soon, and am hoping it can turn on these FET's. They need ultra-low Rds because they will be switching up to 400A, and the board will be in an enclosed, sealed jar, with very high TempCo to the outside. This FET family (DirectFET), appears to have the lowest theta ja I can find. Any alternatives from TI will be appreciated.
