Mô tả chung
ET6296Y is a constant current LED drive circuit with 128 steps linear current control function and 128 steps PWM modulating control function; Built-in 9 independent low-resistance color LED driver channels, and through 6 channel dynamic scanning, it can realize 6×9 led matrix auto-breathing control independently; each channel output current can be adjusted independently by programming the 128 order liner current registers; Through PWM modulation, it can support the RGB LED lights; each low resistance channel can provide maximum 40mA driver current. ET6296Y also has automatic clock synchronization function, it can facilitate two chip extension design.
