LD1072

16-CH LED DRIVER WITH DOT CORRECTION AND 12-BIT PWM CONTROL

TERMINAL

DESCRIPTION

NAME

NO.

GND

Ground

OEB

Blank all outputs. When OEB = H, all OUTn outputs are forced OFF. PWM counter is

also reset. When OEB = L, OUTn are controlled by grayscale PWM control.

Level

triggered

latch

signal.

When

high,

the

LD1072

writes

data from the input shift register to either PWM register (MOD = low) or

DC register (MOD = high). When ST=low, the data in the PWM or

DC registers is held constant and does not change.

CLK

Serial data shift clock

DIN

Serial data input

MOD

Input mode-change pin. When MOD = GND, the device is in PWM mode. When MOD

= VDD, the device is in DC mode.

OUT

<0 :15>

7-22

Constant-current output

ERR

Error output. ERR is an open-drain terminal. ERR goes L when LOD or TEF is detected.

Serial data output.

PWMCK

Reference clock for grayscale PWM control

When DC = VDD, the device is in 6-Bit Mode. when DC = GND, the device is in 8-Bit

Mode and Programmable Adjust Mode.

REXT

Reference current terminal

VDD

Power supply voltage.
