Description
LP8860CQVFPRQ1 is a Texas Instruments LED driver IC. It provides four constant-current LED sinks in a single device, intended for automotive/display backlighting and general lighting. Each channel is individually programmable via external current-sense resistors to set LED current. The device supports dimming (PWM and/or analog dimming) and includes protection features such as LED open/short circuit, overvoltage, undervoltage, and thermal shutdown. It is designed to handle wide input voltages and automotive transients, making it suitable for instrument clusters, backlit LCDs, and signage. The CQVFPRQ1 suffix denotes the specific package and RoHS-compliant variant (QFN Pb-free). Typical configurations use a common supply, four LED strings connected to the channel outputs with sense resistors, and a dimming input to control brightness. For precise electrical characteristics, pinout, and application circuit guidelines, refer to the TI LP8860 datasheet and product page for the CQVFPRQ1 variant.
