What the C8135QP family does
The C8135QP is a 16-channel constant current LED driver IC designed for display applications. It operates on a 3V to 5.5V supply, delivers 0.5mA to 40mA per channel, and supports a 64-level global current gain with ±1.2% typical accuracy. The device features a class SPI interface running up to 30MHz, automatic mode switching, and built-in column blanking. It includes four programmable current knee points to optimize low-power usage and efficiency. The C8135QP handles outdoor or indoor LED displays, handheld device screens, and backlighting for keyboards, mice, and smart speakers. Packaged in a QSOP24, it functions across a temperature range of -40°C to +85°C.
