BL8589

16-Channel Constant-Current LED Driver

FEATURES

DESCRIPTION

The BL8589 is designed for LED display

applications. The device has an input shift

16 constant current sink drivers.



16 constant-current output channels, with

maximum current capability up to 50 mA

each

3.0 to 5.5 V logic supply range

Schmitt trigger inputs for improved noise

Immunity

Power-On Reset , all register bits=0

Low-power CMOS logic and latches

High data input rate: 30MHz

Output current accuracy: between channels

< ±3% and between ICs ±6 %, over the full

operating temperature range

Internal UVLO and thermal shutdown (TSD)

circuitry



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.



APPLICATIONS

The BL8589 is available in a variety of 24-

terminal packages: QFN44-24, which has an

exposed thermal pad, SSOP-24 and TSSOP-

24. All packages are lead (Pb) free and RoHS

compliable.
