Matrix / Segment type LED Driver


PT6951

The PT6951 is a compact LED driver for 90 single LEDs control. The device can be programmed via the I2C or SPI compatible interface. Additionally, each of the 90 LEDs can be dimmed individually with

8-bit allowing 256 steps of linear dimming. The high logic and low logic control threshold are specially designed for white goods and industry application.
