IQSmart AEC-Q100 Qualified IC Load Switches: GLF1111Q & GLF1200Q

Aug. 10, 2023
GLF Integrated's load switches support a wide input voltage range so a single device can be used in a variety of voltage rail applications.

Automotive grade AEC-Q100 IQSmart load switch ICs—GLF1111Q and GLF1200Q—are rated for a wide temperature range (Grade 1 -40 to 257°F (-40 to +125°C)).


The GLF1111Q provides battery-saving leakage current (2nA, typ.). The GLF1200Q features true reverse-current blocking to prevent a backup power source from being discharged when an input node is shorted, working all of the time regardless of on or off state.


Both devices, packaged in a SOT-23-5L, offer easy visual inspection of solder joints and integrated slew-rate control that limit inrush upon turn-on, therefore minimizing 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. And both are offered with an optional output discharge switch.
