GLF71301

Power Distribution Switches, Load Drivers Overview

The GLF71301 is a single-channel load switch from GLF Integrated Power, utilizing IQSmart™ technology for ultra-low power consumption. It operates within an input voltage range of 1.1 V to 5.5 V, with an absolute maximum rating of 6 V. The device supports a maximum output current of 2.0 A and features a typical on-resistance (RON) of 34 mΩ at 5.5 V. Quiescent current (IQ) is typically 1 nA, and shutdown current (ISD) is typically 19 nA at 5.5 V. It includes integrated slew rate control with a controlled rise time of 430 μs at 3.3 V, an internal EN pull-down resistor, and an output discharge switch. The component is housed in a WLCSP-4 package measuring 0.77 mm x 0.77 mm.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific package variant when ordering, as GLF offers different thickness options such as 0.46 mm and 0.35 mm for similar footprints. Confirm that the required current rating aligns with the 2.0 A maximum specification. Ensure design compatibility with the 1.1 V minimum operating voltage. Check for availability of the specific tape-and-reel packaging format if automated assembly is planned.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring minimal footprint and lowest possible leakage current. The integrated slew rate control makes it suitable for systems sensitive to voltage drops during startup. It serves as a direct replacement for competitors like FPF1204, TPS22912, and TPS22915 in designs needing 2 A capacity with ultra-low quiescent current requirements.
