BD26503GUL شرح
System LED Drivers for Mobile Phones
7x17(Max.) Dot Matrix
LED Display Driver
BD26503GUL
Description
BD26503GUL is “Matrix LED Driver” that is the most suitable for the cellular phone.
It can control 7x17(119 dot) LED Matrix by internal 7-channel PMOS SWs and 17-channel LED drivers.
It can control the luminance and firefly lighting of the LED matrix by the setting of the internal register.
It supports SPI and I2C interface.
VCSP50L3 (3.6mm0.55mm height max), small and thin type chip size package.
It adopts the very thin CSP package that is the most suitable for the slim phone.
Features
1) LED Matrix driver (7x17)
It has 7-channel PMOS SWs and 17-channel current drivers with 1/7 timing driven sequentially.
Put ON/OFF(for every dot).
The current drivers can drive 0-20.00mA current with 16 step(for every dot).
64 steps of the luminance control by PWM (common setting for all dots)
Continuous (TDMA off ) lighting function for LED14-LED17
Easy register setting by A/B 2-side map for each dot.
2) Automatic Slope function
Cycle time, Slope time can be set for each dot.
3) 8-direction automatic scroll function.
4) Interface
SPI and I2C BUS FS mode(max 400kHz)Compatibility
For I2C mode, I2C Device address is selectable (74h or 75h)
5) Thermal shutdown
6) Small and thin CSP package
48pin VCSP50L3 (3.6mm0.55mm height max) 0.5mm ball pitch

Except the above
Power dissipation deleting is 12.4mW/ oC , when it’s used in over 25 oC. (ROHM’s standard board has been mounted.)
The power dissipation of the IC has to be less than the one of the package.
