AL5887 - I2C/SPI 36-CHANNEL RGB LED DRIVER

Description

The AL5887 is comprised of 36 programmable LED current channels each with internal 12-bit PWM for color and brightness control through SPI or I2C digital interface.

Features

  • of the AL5887 are controlled via SPI/I2C digital interface. Using a dedicated pin INT_SEL to select either SPI or I2C protocols. The AL5887 has a 30kHz, 12-bit PWM generator for each channel, as well as channel/module independent color mixing and brightness control registers to enable vivid LED effects with zero audible noise. Users can benefit from the device’s ultra-low shutdown IQ Power Saving Mode and easy software programming. The device operates over -40°C to +85°C ambient temperature rang.

AL5887 I2C/SPI 36-CHANNEL RGB LED DRIVER Description The AL5887 is comprised 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. Each channel current can digitally be configured up to 70mA under the thermal limitation of the package. Features of the AL5887 are controlled via SPI/I2C digital interface. Using a dedicated pin INT_SEL to select either SPI or I2C protocols.
