The GLF4000 are integrated power multiplexer switch with dual independent power switches connected to a single output pin to enable seamless transition between two input sources.
The GLF4000 provide an automatic selection mode as well as a manual selection mode by the combination of the logic input pins of EN and SEL. The EN input pin is used along with the select (SEL) input pin to select the automatic switching function, select VIN1 only, select VIN2 only, or turn both switches off. In the automatic selection mode, the GLF4000 automatically select the higher input voltage source out of two input DC power supplies.
The GLF4000 feature an ultra-efficient IQSmartTM technology that offers quiescent current (IQ) and shutdown current (ISD) in the industry. Low RON reduces conduction losses while low IQ and ISD solutions help designers to reduce parasitic leakage current, improve system efficiency, and increase battery lifetime.
The GLF4000 block any cross-conduction current between two input power sources. When the switch is disabled, the GLF4000 prevent the reverse current to the input source from the output at any higher VOUT than VIN condition.
