Hello
Customers are using the CY4533 kit for evaluation.
V_MIN = VMAX = 5V, current is set at ISNK_COARSE = 2A, ISNK_FIN = 0A.
When the PD compatible adapter and the evaluation board were connected with a Type-C cable, the VBUS Power LED emitted light and the 5V voltage could be confirmed from the VBUS line.
Even when a PD-incompatible Type A adapter and evaluation kit are connected with an A to C cable, the VBUS Power LED emits light and is output from the VBUS line at a voltage of 5V.
(Maximum output of Type A adapter is 5V / 2.4A)
After checking the kit guide, it was recognized that the Fault pin was set up (red LED was lit) and 5V / 900mA was output from Safe_5V Output.
However, the output from Safe_5V Output could not be confirmed.
Why is this?
Best Regards
Hayato
