PRODUCTION DATA
Electronic devices are becoming smarter, requiring to use larger quantity of LEDs for animation and indication purpose. A high performance LED matrix driver is required to improve user experience with small solution size.
The LP586x devices are a family of high performance LED matrix drivers. The device integrates 18 constant current sinks with N (N = 1/2/4/6/8/11) switching MOSFETs to support N × 18 LED dots or N × 6 RGB LEDs. The LP5866 integrates 6 MOSFETs for up to 108 LED dots or 36 RGB LEDs.
The LP5866 supports both analog dimming and PWM dimming methods. For analog dimming, each LED dot can be adjusted with 256 steps. For PWM dimming, the integrated 8-bit or 16-bit configurable PWM generators enable smooth and audible-noise-free dimming control. Each LED dot can also be arbitrarily mapped into 8-bit group PWM to achieve dimming control together.
The LP5866 device implements full addressable SRAM to minimize the data traffic. The ghost-cancellation circuitry is integrated to eliminate both upside and downside ghosting. The LP5866 also supports LED open and short detection functions. Both 1-MHz (maximum) I2C and 12-MHz (maximum) SPI are available in LP5866.
