GENERAL DESCRIPTION
AW21009G is a 9-channel multi-function LED
driver. Each channel has individual 8-bit DC current
setting for color-mixing and maximum 12-bit PWM
resolution for brightness control. The global current
of each channel is recommended to be 40mA
configured via register and external Resistor REXT.
Group control mode, autonomous breathing pattern
and rapid RGB control mode are provided for
flexible, high efficiency lighting effect programming
and fast display updating.
Programmable phase-shifting and spread spectrum
technology are utilized to reduce EMI and audible
noise caused by MLCC when LEDs turn on or off
simultaneously.
AW21009G can be turned off with minimum current
consumption by either pulling the EN pin low or
using the software shutdown feature.
AW21009G is available in QFN 3mmX3mmX
0.75mm-20L package. It operates from 2.7V to 5.5V
over the temperature range of -40°C to 105°C.

NOTE1: Conditions out of those ranges listed in "absolute maximum ratings" may cause permanent damages
to the device. In spite of the limits above, functional operation conditions of the device should within the ranges
listed in "recommended operating conditions". Exposure to absolute-maximum-rated conditions for prolonged
periods may affect device reliability.
