The GLF4012 is an ultra-low IQ integrated power multiplexer IC with dual independent power switches connected to a single output pin to enable seamless transition between two input sources. The GLF4012 features symmetrical power FET characteristics. Channel 1 (VIN1) and channel 2 (VIN2) provide ultra-low conduction resistance to support 6 A continuous current capability. It is an ideal solution for a power system with an internal back up power source.
The GLF4012 provides an automatic selection mode, a manual selection mode and VIN1 preference mode. The switching of these three modes is executed by combining the S1 and S2 pin settings. The S1 input pin has an internal threshold voltage to offer a preference to select the channel 1 (VIN1) power source. In the automatic input selection mode, the GLF4012 automatically selects a higher input voltage source between two input power sources.
