Hi Anze,
I suspect M2 Mosfet is damaged by voltage spikes during its turn off process.
If you are still using CSD17578Q3A as M2 Mosfet I would try to add gate resistor of around 100 Ohm, it should extend its turn off time and limit
voltage transients…

Part Number: CSD16411Q3 Other Parts Discussed in Thread: CSD17578Q3A Hi,
We want to use CSD16411Q3 as a substitute for CSD17578Q3AT They look technically same but need your confirmation if we can use it as a drop in replacement.
Please help.
Thank…

Hi Tiger,
I did small changes in my design to charge lithium ion battery pack(18.8V/6A).
While i am powering (18.8V/5A)the board without load, got the output with small voltage drop.
but when i tried to power up the board with load(battery pack…
Hey Hugo,
The recommended replacement for the CSD1755Q3A is the CSD17578Q3A.
The HIDRVx and LODRVx pins output up to 6V across the Gate-Source of the power MOSFETs. So MOSFETs with +/-10V to +/-20V rated VGS should be fine.
