PRODUCT DESCRIPTION
The GLF1401 / GLF1403 is a dual channel integrated load switch with the VariRiseTM technology which provides the programmable slew rate of variable output voltage rising times.
Each channel of the GLF1401 / GLF1403 operates independently over an input range from 0.6 V to 5.5 V and supports 6 A maximum continuous output current per channel. The GLF1401 / GLF1403 feature supports some of the lowest RON, quiescent currents (IQ) and shutdown currents (ISD) in the industry. Low RON reduces conduction losses, while low IQ and ISD solutions help designers to improve system efficiency.
The SR input pin allows the user to add an external capacitor to set the slew rate of the switch output voltage to a specific value for a given output capacitance. It limits inrush currents during turn-on, helping to minimize voltage drop.
