I'm trying to understand the following circuit which is taken from the TI's TIDA-010216:
I don't understand the role of Q19, D29, D30 and Q33 in the circuit. According to this post, it seems that Q19, D29 and D30 are used in order to prevent OUTA pin from PACK- negative swings but I'm not sure about that. Also the role of Q33 is still unknown to me.
The other problem is related to the pre-discharge circuit. According to the block diagram of the TIDA-010216, current-limiting resistors R118 and R119 should be connected to the PACK-, which is reasonable to me, but in the provided schematic that's not the case:
