LP3943ISQ

IC LED DRIVER PS I2C 25MA 24WQFN

Manufacturer: Texas Instruments

Categories: LED Drivers

Quality Control: Learn More

Texas Instruments LP3943ISQ is a 16-output LED driver IC featuring a shift register topology. This power switch device offers I2C and SMBus dimming capabilities for precise control of LED current, up to 25mA per channel. Designed for surface mount applications, it is supplied in a 24-WQFN (4x4) package, presented on tape and reel. The LP3943ISQ operates within a supply voltage range of 2.3V to 5.5V and is rated for operation from -40°C to 85°C. Its internal switches and shift register architecture make it suitable for applications requiring multi-channel LED illumination control, such as camera flash systems.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
