3 Description
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-noisefree
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 ghostcancellation
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.
