Littelfuse, Inc. 5 V, 2 A Ultra Low Consumption Load switch with Slew Rate Control LQ05022QCS4

The LQ05022QCS4 is an ultra-efficiency, 2 A rated, load switch with integrated slew rate control. The best in class efficiency makes it an ideal chose for use in IoT, mobile, and wearable electronics. The LQ05022QCS4 supports the lowest quiescent current (IQ) and shutdown current (ISD) in the industry. Low IQ and ISD solutions help designers to reduce parasitic leakage current, improve system efficiency, and increase battery lifetime. The LQ05022QCS4 integrated slew rate control can also enhance 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 currents during turn-on to minimize voltage droop. The LQ05022QCS4 load switch device support 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 reduce operating cost. The LQ05022QCS4 load switch device is small utilizing a chip scale package with 4 bumps in a 0.97 mm x 0.97 mm x 0.55 mm die size and a 0.5 mm bump pitch. Ultra-low IQ: 7 nA Typ @ 5.5 VIN Ultra-low ISD: 28 nA Typ @ 5.5 VIN Low RON = 31 mΩ Typ @ 5.5 VIN IOUT max = 2.0 A Wide input range: 1.1 V to 5.5 V, 6 Vabs max Controlled rise time: 335 μs at 3.3 VIN Internal EN pull-down resistor Integrated output discharge switch Ultra-small: 4 bumps in a 0.97 mm x 0.97 mm x 0.55 mm WLCSP
