UCD3138: Reverse Constant Current

Part Number: UCD3138

Hello all,

I am trying to make a bidirectional converter. In order to measure the current for input and output, I used bidirectional hall effect sensor. In forward direction, I implemented the constant current mode and everything is fine with that. However, in reverse direction, EADCDAC reference is below the current feedback value during Constant Voltage Mode which is a much different case than the forward direction case.

I tried to use D_ENABLE bit in the DPWMCTRL0 register but I guess I failed because I saw nothing as a PWM pulse. How can I solve this problem or is there any reference code/manual for reverse current limitation?

Regards,

Steve
