BQ76952: TIDA-010208 10s-16s Battery Pack reference design

Part Number: BQ76952
Other Parts Discussed in Thread: TIDA-010208

Tool/software:

Hello, 

I have a question about document TIDA-010208 (10s-16s Battery Pack reference design).

I couldn't understand why there is a D38 zenner diode and what the function of this zenner is.

Also, I don't understand what the Q29 mosfet circuit does, I guess it is a protection circuit? is it?

My battery structure is 1P15S LFP and discharge current is max 100A, charge is max 20A.


So, can I use this mosfet driver circuit (reference design circuit) in my own design?

Please help me,
