TPS2112PW General Description

In contrast, traditional power multiplexers often struggle with supply transitions, resulting in inefficient energy transfer and potentially harming your device. The TPS211x family elegantly solves this problem by offering robust cross-conduction blocking and reverse-conduction blocking capabilities. This means you can confidently design complex power multiplexer applications, knowing that the TPS211x will handle even the most demanding situations with ease
