BD6086GU

●Description

BD6086GU is a composite LED driver best-suited for mobile phone display.

With an analog illumination intensity sensor connected, this LED driver mounts an auto luminous control (ALC) function

capable of automatically adjusting the backlight current depending on an ambient illumination intensity to reduce the set

power consumption. With a key backlight driver mounted, this driver enables the ON/OFF setting to be made depending on

the ambient illumination intensity. In addition, this driver realizes an eye-catching display through the use of two RGB LED

drivers supporting a slope control function.

With two channels of variable output type regulators mounted, this driver can be used for LCD and camera. This driver

eliminates the need for additional wirings on a flexible substrate through the GPIO mounted.

The DC/DC module adopts a charge pump system and rarely uses a coil. Furthermore, it employs a VCSP85H4 (4.5mm²

0.5mm pitch) chip size package for compaction and thinness.

●Futures

1) LED Driver (7ch) for LCD Backlight

・Incorporates 4 channels for main settings and 3 channels optionally selectable for either independent control or main

setting depending on register settings.

・Provides a driver assigned for main settings with various functions such as an automatic current value adjustment

function by an illumination intensity sensor, a slope control function against current value variation, an LED current

value adjustment function for reflecting a setting value in a register through external pin synchronization and an LED

current value adjustment function through external pin PWM input.

2) RGB LED driver (dual driver)

・Incorporates a slope control function (capable of controlling dual drivers independently)

・Capable of selecting (setting) a battery or DC/DC output module as a destination (register setting)

・Capable of using one driver for GOP output mode (register setting)

3) Illumination intensity sensor interface

・Incorporates various functions such as a sensor bias adjustment function, an ADC with an average filter, a gain/offset

adjustment function and an LOG conversion function so that options can be increased for illumination intensity

sensors (Photo Diode, Photo Transistor, Photo IC (Linear/LOG)).

・Incorporates an auto gain switching function for suppressing an illumination intensity sensor current at high

illumination intensity and improving sensitivity at low illumination intensity

・Capable of customizing an LED current value according to a table setting.

4) Built-in regulator (2 channels)

・REG1 2.8V Iomax=150mA

・REG2 1.5V/1.8V Iomax=150mA

・REG1, REG2

Low power consumption mode available

Both can be controlled independently via external pins.

5) Charge pump system DC/DC

・Supports an output voltage fixed mode function (3.9V/4.2V/4.5V/4.8V)

・Mounts a soft start function, an overvoltage protection function (auto recovery type) and an overcurrent protection (auto recovery)

6) Key backlight controller

・Capable of ON/OFF control depending on an ambient illumination intensity

・Capable of adjusting key backlight brightness via MAX DUTY setting

・Capable of making an fade-in/fade-out setting via PWM

7) Built-in general-purpose port (4 channels)

・GPIO4ch

・Permits the selection of a complementary or open drain for output.

8) Thermal shutdown

9) I²C BUS Fast mode support (max. 400 kHz)
