LV5239TA Datasheet, PDF (1/28 Pages) ON Semiconductor – 24-channel LED Driver

LV5239TA

Bi-CMOS LSI

24-channel LED Driver

Overview

The LV5239TA is a 24-channel LED driver IC that is capable of switching

between constant-current output and open drain output. It enables

2-wire/3-wire serial bus control (address designation) to be set arbitrarily

using an external pin. Also possible are 24-channel LED ON/OFF control

and the setting of the PWM luminance in 256 steps.

Up to 32 driver ICs can be connected using the slave address setting pins.

Function

ï· 24-channel output constant-current LED driver/open drain output LED driver (selected by using an external pin).

Supports separate ON/OFF setting for each LED output, high withstand voltage (VOUT<42V).

ï· In the constant-current mode (OUTSCT: L), the reference current is set by the value of resistor connected to the

external pin (RT1).

Built-in D/A (3 bits) for switching current level â¦ 6.40mA to 32.40mA (RGB drive).

Constant current (IO max=50mA) for full-color LEDs ï´ 24 channels.

ï· In the open drain mode (OUTSCT: H), high current drive

(IO max=100mA) ï´ 24 channels

ï· In the constant-current mode (OUTSCT: M)

Only RGB7, RGB8 is open drain (IO max=100mA)

ï· Luminance adjustment using internal PWM control (256 steps), It copes with independent PWM control for each

LED output.

ï 8-bit PWM luminance dimming (0% to 99.6%)

ï 8-phase PWM

ï· Selection of 2-wire/ 3-wire serial bus control signals enabled (switching using an external pin).

ï Schmitt trigger input (3.3V/5V)

ï· Slave addressing (5 bits, connection of up to 32 driver ICs possible)

ï· Input Power supply supports 12V

ï Internal reference output terminal (5V)

ï· Low current consumption

ï· Output malfunction protection circuits

(thermal protection function, UVLO detection protection function, Power on RESET)
