AL5887 Description
The AL5887 is prised of 36 programmable LED current channels each with internal 12-bit PWM for color and brightness control through SPI or I2C digital interface. AL5887 is ideal for up to 12 RGB LED modules lighting applications with 3 programmable banks (A, B, C) for software control of each color. An external resistor can set up the global output current of all 36 channels.
