Electronic devices are becoming smarter, requiring to use larger quantity of LEDs for animation and indication purposes and high performance LED matrix driver is required to improve user experience with small solution size.
The LP5867 is a high performance LED matrix drivers. The devices integrate 6 constant current sinks with N (N = 7) switching MOSFETs to support N × 6 LED dots or N × 2 RGB LEDs. The LP5867 integrates 7 MOSFETs for up to 42 LED dots or 14 RGB LEDs.
The LP5867 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 LP5867 device implements full addressable SRAM to minimize the data traffic. The ghost-cancellation circuitry is integrated to eliminate both upside and downside ghosting. The LP5867 also supports LED open and short detection functions. Both 1MHz (maximum) I2C and 12MHz (maximum) SPI are available in LP5867.
