BD6085GUL

●Description

BD6085GUL is Multi-Function LED Driver that is the most suitable for the cellular phone.

It has many functions that are needed to "the upper side" of the cellular phone.

●Features

1) Total 7LEDs driver for LCD Backlight (Main/Sub) and LED Flash

It can set maximum 30mA by 32 steps (Current DAC) for Main/Sub Display

It can set maximum 360mA for Flash LED driver

(It has 3 channels LED driver at maximum 120mA/ch for Flash.)

The number of lighting for Main/Sub/Flash LED can be set up grouping by register.

Ex. ) 4LEDs / 0LED / 3LEDs

4LEDs / 1LED / 2LEDs

4LEDs / 2LEDs / 1LED

4LEDs / 1LED / 1LED

5LEDs / 1LED / 1LED

5LEDs / 0LED / 2LEDs

6LEDs / 0LED / 1LED

It can use the 1LED Flash module to 3LED Flash module.

Normal mode = maximum 30mA/ch, Flash mode = x4 normal mode (for 3ch LED).

The grouping of LED is independently controlled by register.

2) 4ch Series Regulator (LDO)

It has selectable output voltage by the register.

LDO1,LDO2 : Iomax=200mA

LDO3,LDO4 : Iomax=150mA

3) Charge Pump DC/DC for LED driver

It has x1/x1.33/x1.5/x2 mode that will be selected automatically.

Soft start functions

Over voltage protection (Auto-return type)

Over current protection (Auto-return type)

4) Thermal shutdown (Auto-return type)

5) I²C BUS FS mode(max 400kHz)Write/Read

6) VCSP50L3(3.30mm×3.30mm, 0.55mm) Small and thin CSP package
