The AW20036 is a 3×12 matrix LED driver programmed via an I 2 C compatible interface. The brightness of each LED is independently controlled by FADE and DIM parameter. Three integrated pattern controllers provide auto breathing or group dimming control. Each pattern controller can work in auto breathing or manual control mode. All breathing parameters including rising/falling slope, on/off time, repeat times, min/max brightness and so on are configurable. Each LED’s FADE parameter can sourced from any one of the 3 pattern controllers optionally. Fast display refreshing is supported, multiple parameters(DIM, FADE and PAT) for each LED can be configured together through one I 2 C write without switching internal register page. 1MHz I 2 C-compatible interface is provided with 4 selectable addresses by AD pin. Multiple devices clock synchronization can be implemented by configuring the function of pin CLKIO AW20036 is available in QFN4mmX4mm-32L package.
