TPS22990: TPS22990N Reverse Current Blocking

Kirk Milling

Part Number: TPS22990

Since CT is pinned out and available, are there any functional issues with implementing reverse current blocking by using two TPS22990N's in series similar to how it implemented with the TPS22976N (Datasheet Figure 38)?

Hi Kirk,

Good question! No issue here, you can connect two of these devices in series for back to back operation. This way when the devices are off, there will be no reverse current flow.

Thanks,
