The GLF71321 is an ultra-efficienct, 4A rated, Load Switch with integrated slew rate control. With a focus on Low RON, its best in class efficiency makes it an ideal choice for higher current applications. The GLF71321 is ideal for use in IoT, mobile, and wearable electronics.
The GLF71321 features ultra-efficient IQSmartTM technology that 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 reduce parasitic leakage currents, improve system efficiency, and increase battery lifetimes.
The GLF71321 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 GLF slew rate control specifically limits inrush currents during turn-on, helping to minimize voltage droop.
GLF71321 Load Switch devices support an industry leading wide input voltage range, helping to improve operating life and system robustness. Furthermore, one device can be used in multiple voltage rail applications, helping simplify inventory management and reduce purchasing, and operating costs.
GLF71321 Load Switch devices are small. They use chip scale packaging, utilizing 6 bumps, in a 0.97mm x 1.47mm die size with 0.5mm bump pitch.
