1/80 www.rohm.com 2011.04 - rev. a ? 2011 rohm co., ltd. all rights reserved. system led drivers for mobile phones 13leds alc * flash and illumination (*alc : auto luminous control) BD6086GU description BD6086GU is a composite led driver be st-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 ba cklight 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 (4.5mm 2 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 opt ionally 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 adjust ment 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 suppressi ng an illumination intensity sensor current at high illumination intensity and improving sens itivity 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 low power consumption mode available ? reg2 1.5v/1.8v iomax=150ma low power consumption mode available ? reg1, reg2 both can be controlled independently via external pins. 5) charge pump system dc/dc ? supports an output voltage fixed mo de 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 recov ery) 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) i 2 c bus fast mode support (max. 400 khz) * radiation-proof is not designed. * this description is subject to change without a prior notice. * this description is not a delivery specification. no.11041eat16
