The LQ05041QCS6 is an ultra-efficiency, 4 A rated, integrated load switch with integrated slew rate control.

The LQ05041QCS6 features an ultra-efficient technology that supports the lowest RON, 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 LQ05041QCS6 integrated slew rate control greatly enhances system reliability by mitigating bus voltage swings during switching events. Where uncontrolled switches can generate high inrush currents that result in voltage droop and/or bus reset events, the slew rate control specifically limits inrush current during turn-on to minimize voltage droop.

The LQ05041QCS6 load switch device supports an industry leading wide input voltage range and helps to improve operating life and system robustness. Furthermore, one device can be used in multiple voltage rail applications which helps to simplify inventory management and reduces operating cost.

The LQ05041QCS6 load switch device is small utilizing a chip scale package with 6 bumps in a 0.97 mm x 1.47 mm x 0.55 mm die size and a 0.5 mm pitch.
