Other Parts Discussed in Thread: USB-C-PD-DUO-EVM
Hi,
We would like to know if TPS65987DDH has FW OCP (overcurrent protection) for 9V/15V/20V.
Based on the app notes http://www.ti.com/lit/an/slva994/slva994.pdf, it mentioned 5V examples but there are no 9V/15V/20V examples. Inside the app note, it also mentioned that Overcurrent Clamping is only implemented when the TPS65987DDH is sourcing 5 V on VBUS.
Our customer set the source capabilities setting of 15V 3A 150% peak current. When connected to one PD Sink A, the cutoff (FET open) current was 4.6A, and when connected to another PD sink B, the cutoff current was 5.5A. Do you know why there is difference in the cutoff current when using the same 987DDH device?
Thanks.
