AW20198SG is an 18x11 matrix LED driver programmed via an SPI 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 or group dimming control. Each pattern controller can work in auto breathing or 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 or off simultaneously.
AW20198SG can be turned off with minimum current consumption by either pulling the EN pin low or using the software reset.
AW20198SG operates over the temperature range of -40°C to +105°C.
