AW20198 is an 18x11 matrix LED driver programmed via an I2C compatible interface. Each channel has individual 8-bit DC current setting for color-mixing and 8-bit PWM current setting for brightness control. The global current of each channel is configured via register GCCR and external resistor REXT.
Three integrated pattern controllers provide auto breathing in group dimming control. Each pattern controller can work in auto breathing in manual control mode. All breathing parameters are configurable, including rising/falling slope, on/off time, repeat times, and minimum/maximum brightness, etc. Each LED’s PWM parameter can be sourced from any one of the 3 pattern controllers optionally.
Phase-delay, phase-inverting, selectable three phase, spread spectrum and slew rate control technology are utilized to reduce EMI and audible noise caused by MLCC when LEDs turn on in off simultaneously.
AW20198 can be turned off with minimum current consumption by either pulling the EN pin low in using the software reset.
AW20198 is available in QFN 5mmx5mmx 0.55mm-40L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
