General Description
AW2013 is a product of 3-channel LED
driver supporting auto breathing mode with
I2C interface in AWINIC LED driver product
line. It can drive 3 individual LEDs or one
group of RGB.
AW2013 drives LEDs with common anode,
constant current. The brightness can be
modulated in PWM with 256 steps. The
output current can be configured in 4 levels:
15mA、10mA、5mA、0mA(default)。
AW2013 supports fade-in and fade-out
effect for brightness control. There are two
modes: the Direct PWM Control mode and
One Short Programming mode. In the one
short programming mode, it's flexible to set
the breathing speed, timing, brightness and
repeat times.

After power-up reset operation finished, the ISR.4(PUIS) will be set to “1”. The INTN port will be driven low to inform master AW2013 has finished the power-up operation and is ready to work. This bit can also be used to check whether there’s a power-down event after reading this register last time. - Page 10 31h~33h) to “1”. In this mode, AW2013 can modulate the brightness of LED according to the programmed timing in a breathing cycle. T0~T4 define the 4 key timing in a breathing cycle. T0 is a delay time for starting, T1~T4 composite a full cycle.
