概要

Description

LP8556SQE-E00/NOPB is a six-channel, constant‑current LED backlight driver IC for LCD panels. It provides six programmable current sinks to drive LED strings in backlight modules, with per-channel current settable via registers (and/or external resistors) for uniform brightness. Dimming support includes PWM and analog dimming, typically controllable through an I2C-compatible interface for brightness, current, and fault reporting. Protection features commonly include overcurrent, short-to-LED, undervoltage/overvoltage lockout, thermal shutdown, and soft-start to reduce LED stress. The device integrates a driver/regulator capable of driving LED strings from the system supply (some variants support boost/buck-boost to accommodate higher LED voltages). The SQE-E00 designation indicates a specific package/variant, and NOPB means Pb-free, RoHS-compliant packaging. Typical applications are LCD backlight assemblies in TVs, monitors, tablets, and portable displays requiring precise, dimmable LED current. For exact pinout, numbers, and electrical characteristics, reference the official LP8556 datasheet.

Features

Concise features of LP8556SQE-E00/NOPB:
- 6-channel constant-current LED sink driver for LCD backlights
- I2C control interface with configurable address
- Programmable current per channel; global and per-channel dimming (PWM)
- 256-step dimming resolution for smooth brightness control
- Fault protection: open/short LED detection, overcurrent protection, thermal shutdown
