Datasheet
LED Driver with I²C Compatible
and 3-wire Serial Interface
for 8×16 LEDs in Dot Matrix
BU16501KS2
General Description
BU16501KS2 is “Matrix LED Driver” that is the most
suitable for Home Appliance.
It can control 8x16 (128 dot) LED Matrix by internal
8-channel PMOS SWs and 16-channel LED drivers.
It can control the brightness in each dot by the setting
of the internal register.
It supports SPI and I²C interface.

Features
 LED Matrix driver (8x16)
 It has 8-channel PMOS SWs and
16-channel current drivers with 1/8
TDM timing driven sequentially.
 Put ON/OFF (for every dot)
 The current drivers can drive from 0
to 20.00mA current with “16” steps(for
every dot)
