company blog about Recycled Automotive LED Driver TLC69618QPWPRQ1 Mini-LED Matrix Local Dimming Backlight Driver

Shenzhen Mingjiada Electronics Co., Ltd. recycles automotive LED driver TLC69618QPWPRQ1 Automotive 128-partition Mini-LED matrix local dimming backlight driver with 60mA 16-channel current trap.

TLC69618QPWPRQ1 Device Overview

The TLC696x8-Q1 is a family of LCD local dimming backlight drivers compatible with the TLC696x0-Q1, a scanning MOSFET controller that enables 2/4/8 time division multiplexing control. Each device integrates 16 constant-current traps with correspondingly sized SRAM for brightness storage. The devices are interconnected in a daisy-chain topology via a two-wire serial interface and support up to 1024 devices for more than 32,000 local dimming zones.
