PT6951 - LED Driver

General Description

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.

Key Features

  • CMOS technology.
  • Low power consumption.
  • 3-wire SPI-bus interface (DIN, CLK, STB).
  • 2-wire I2C interface (SCL, SDA).
  • 90 LEDs in dot matrix.
  • 256-Step dimming setting for all individual LED.
  • Fading enable for all individual LED.
  • Constant-Current LED Segment Drive.
  • Serial interface for Clock, Data Input, Strobe Pins and low voltage operation ability when user’s MCU power supply is 3.3V.
  • Integrated Oscillator Circuit.
  • Available in 20-pin, TSSOP.
