BQ25730: Switching action of 4 MOSFETS

Part Number: BQ25730
Other Parts Discussed in Thread: BQ24800,

Tool/software:

Dear sir, we have been using the BQ25730 IC in our projects, but we are observing differences in switching actions of MOSFET's which includes

1) HiDrv1 switching in boost mode while it is supposed to act as ON switch

2)HiDrv2 switching in buck mode which is supposed to act as ON switch

3)Also Lodrv1 & Lodrv2 both signals are switching in both buck and boost modes (with no load/ light load) out of two only one was supposed to act as open switch and the other as switching in two modes but output voltage is same as configured voltage in charge voltage register.

4)In Boost mode with load we are facing I2C communication issues.(data received through communication is junk/error data )

attached the test report please let us know the solution for this.
