The Texas Instruments TPS22985EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the TPS22985: Supply Selection IC. The TPS22985 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 TPS22985 has two modes of operation, Normal and
Control.
The EVM contains one TPS22985 - Supply Selection IC (See
