The Hi7011 with SOP-8 LED Drivers ROHS is a LED driver IC manufactured by Hichips. It is an 8-pin surface-mount package containing a low-voltage (3V-5V) operation low-side constant current pulse-width modulation (PWM) driver. This device includes over-voltage/reverse-voltage protection, output current-compensation, programmable K factor and soft-start. The output can sink up to 90mA per channel, and the supply voltage range is from 3V to 5V. The device is RoHS compliant, meaning it is free of hazardous substances such as lead, cadmium, mercury, hexavalent-chromium, polybrominated-biphenyls, and polybrominated-diphenyl-ethers.
