TMS320F280023C: Design OCP Hiccup mode

Hi Soosan,

Thanks for reaching out on the E2E forums. We don’t currently have an example of implementing hiccup mode for overcurrent protection but, depending on your topology, it sounds possible to do with the CLB peripheral.

You could implement this by passing in your drive and OC detect signals into the CLB tile. You could make use of the FSM to have a pass-through state and a hiccup state, with some OC detect trigger used to switch between the two states. It sounds like you would have to configure the CLB to override your drive signal outputs directly. In pass through state you can directly feed your drive signals through the tile unchanged, while in hiccup state, you can use the counter to do some periodic toggling depending on what match value is configured and then the output of the CLB would override the drive signals

Please reach out if you have questions about this

Regards,
Peter
