Hello Harish,

Could you please let us know the reason you need to know the internal ESD structure?

ESD Gun validation has been performed on every pin of the device and is showing robustness using the schematics as described in the datasheet.

BR, Tomas

Dear Tomas,

We are in the process of Designing and developing of BMS+Battery pack for an EV. Please note we have signed Mutual NDA with NXP.

Our BMS is high voltage in the range of 270+ volts.

We are using MC33771C and MC33772C in our BMS.

While looking in-depth at Hot-plug performance and protection for BMS we were able to find the internal ESD structure for MC33771C in the application note( AN12576) and further details in MC33771C's latest datasheet ( Rev 6.0 10 May 2021) on how to build a robust hot plug protection.

But we did not find detailed information regarding MC33772C. Hence if we can get the Internal ESD structure of MC33772C we will design hot plug for additional safety in our schematic for MC33772C.

Regards,

Harish
