Part Number: EMB1499Q
Is there any bi-directional current DC-DC controller available with TI which can support up to 100V stack voltage?. Existing EMB1499Q can support up to 60V stack voltage?. In our application we are using 24 li-ion cells in series. We would like to implement TI based active cell balancing with 4xSwitch matrix driver (Emb1428q) & 2xDC-DC isolated bi-directional controller(Emb1499q). Please see the attachment is this feasible and scalable?

In reply to David Wiest Jr:
Thanks for the reply, I do considered 2x12 cells and it looks feasible scalability point of view. Is there any limitation or constraint to connect the transformer primary side of forwad DC DC converter to the same 12-cell stack voltage?

Please message me - I have a couple preliminary app notes that may be helpful for you while designing. Off of the top of my head, I think it should be a fairly simple conversion to balance cells back to the module. We have a TI reference design that is older, but does use the EMB1499 in the way you are asking (TIDA-00239)

There is also the EM1402/TIDA-00817 to reference. This is a more modern version
Indeed it's helpful. Could you please share the application notes which would be useful for automotive application (electric vehicle)
