LED驱动芯片 PT6951 普诚科技 原厂原装
DESCRIPTION
The PT6951 is a compact LED driver for 90 singleLEDs control. The device can be programmed via theI2C or SPI compatible interface. Additionally, each ofthe 90 LEDs can be dimmed individually with8-bit allowing 256 steps of linear dimming. The highlogic and low logic control threshold are speciallydesigned for white goods and industry application.
