Other Parts Discussed in Thread: TPS22953, LMR14030, TPS62813
I have used two TPS22953s for output shorting, with the chip enable controlled by MOSFETs for switch selection. The initial intention of the design was to implement power source switching, but during the switch there is a significant power drop at the backend, causing the backend operations to briefly interrupt. I have two questions:
- If the reverse protection is disabled on the TPS22953, is it possible to enable both at the same time, so that when one power source is disconnected, the other can directly continue without causing the backend to reset during the switch? This would be similar to the effect of two diodes in series.
- Based on my application requirements, could you please help me review the circuit design to see if there are any improvements to be made? The primary power supplies used are LMR14030 and TPS62813.
