General Description

IS31FL3224 is an LED driver with 24 high voltage (16V) constant current channels.

Each channel can be pulse width modulated (PWM) with 7-bit/8-bit precision for smooth LED brightness control.

The maximum output current of each channel is designed to be 40mA, which can be adjusted by three 7-bit/8-bit global control registers group (one group for R for CS 3×n, one group for G for channels 3×n+1, and one group for B for channels 3×n+2, n=0~7, for example: one group for R is CS0, CS3, CS6 … CS21.

Key Features

  • VCC= 3.0V to 5.5V.
  • Support 24 constant current channels, tolerate up to 18V, nominal operation voltage up to 16V.
  • Constant-current output range: 40mA.
  • Current output range (open drain (OD) mode): 100mA× 24 channels.
  • Interface (MODE pins) - DSB (Daisy Chained Serial Bus, 2MHz) - HSB (High Speed Series Bus: 10MHz) - SPI (12MHz) - I2C (1MHz).
  • For DSB and HSB - Built-in PWM generator: 7-bit/ch - 7-bit × 3 global current adjustment.
  • For.
