Our customer is doing feasibility study.
They are using Half Bridge operation like a Figure 22 (attached file
) in the datasheet (P16 Rev.G) .
Their system power sequence is unique.
It is Vbus first power on and next VDD1 power on. (The time sequence is not disclose.)
Does the condition may cause permanent damage to the secondary circuit under each VDDA or VDDB? (While VDD1 is unpowered and Vbus is only powered.)
