12-channel LED driver from Diodes Incorporated

▤ Summary

It features 12 open-drain outputs that are rated to 24V and sink up to 60mA of high-accuracy current with a fast transient response. The device’s two-wire serial interface sends grayscale data to the function-control registers that store the configuration information. It controls grayscale resolution and clock frequency, current output waveform selection, and internal-latch function. The AL58221 uses a clock duty recovery technique with pulse retiming to support a longer distance connection. Within the same LED driver family, the recently introduced AL58263 is a 16-channel device with 16-bit PWM grayscale dimming control for higher resolution and larger display panel applications.
