BL8589

BL8589 16-Channel Constant-Current LED Driver DESCRIPTION The BL8589 is designed for LED display applications. The device has an input shift register with corresponding data latches and 16 constant current sink drivers. The device support digital input with internal shift registers and latches, hence can be controlled directly by microprocessor-based systems. With a standard 3.3V or 5V logic supply, serial data input rates can reach up to 30 MHz. The BL8589 allows user defined maximum LED drive current level which is set by a single external resistor. Chip build-in serial data output permits cascading of multiple devices in applications requiring additional drive lines. The BL8589 is available in a variety of 24terminal packages: QFN44-24, which has an exposed thermal pad, SSOP-24 and TSSOP24. All packages are lead (Pb) free and RoHS compliable.
