Description
The SLG59H1401C is a high-voltage GreenFET load switch designed for OR’ing or manual power multiplexer (MUX) applications. The part includes two 3A-rated load switches that are well suited for a variety of systems having multiple power sources. The device automatically detects, selects, and seamlessly transitions between available inputs. Additionally, manual switching between two power rails is allowed.
