Description

AW20144SQPY is an 18x8 matrix LED driver programmed via SPI or I2C compatible interface. Each channel has individual 8-bit PWM current setting for brightness control. The global current of each channel is configured via external resistor REXT. 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. AW20144SQPY can be turned off with minimum current consumption by either pulling the EN pin low or using the software reset. AW20144SQPY is available in EQFP 7X7-48L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +105°C.
