The Texas Instruments TPS22986EVM evaluation module (EVM) helps designers evaluate the performance of the TPS22986 Supply Selection IC. The TPS22986 selects a 3.3V input from two available supplies and connects the chosen input to two outputs, OUTA and OUTB. If a 3.3V supply is not present, the outputs become high impedance. The TPS22986 has two modes of operation, Normal and Control. The EVM contains one TPS22986 IC.
