The IC load switches are the newest members of the I_QSmart range. The AEC-Q100 qualified ICs have a wide temperature range of -40 to 125°C.

The GLF1111Q provides industry-leading, battery-saving leakage current, claims the company, at 2nA, typical while the GLF1200Q features true reverse-current blocking, which prevents a backup power source from being discharged when an input node is shorted. The GLF1200Q works all of the time regardless of on or off state, adds the company.

Applications for both low power load switches include infotainment and cluster display systems, diagnostic systems, passive entry/start systems (PEPS), customer premise equipment (CPE), face recognition systems and intelligent cockpit and autonomous driving applications.

Both the GLF1111Q and GLF1200Q I_QSmart devices are packaged in a SOT-23-5L for easy visual inspection of solder joints. Both also feature integrated slew-rate control that limit inrush upon turn on, minimising the effects of voltage droop.

Each load switch IC supports a wide input voltage range (1.5 to 5.5V), meaning a single device can be used in a variety of voltage rail applications, which helps to simplify inventory management. Both ICs are offered with an optional output discharge switch.

 “The GLF1111Q and GLF1200Q address the ever-expanding, evolving range of automotive electronic systems that require a high performance load switch with a wide ambient operating temperature range to assure reliable, long-term operations,” comments Eileen Sun, president, and CEO at GLF Integrated Power.
