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 (3.6mm □0.55mm 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 I 2C BUS FS mode(max 400kHz)Compatibility ・For I 2C mode, I2C Device address is selectable (74h or 75h) 5) Thermal shutdown 6) Small and thin CSP package ・48pin VCSP50L3 (3.6mm□ 0.55mm height max) 0.5mm ball pitch *This chip is not designed to protect itself against radioactive rays. *This material may be changed on its way to designing. *This material is not the official specification. ●Absolute Maximum Ratings (Ta=25 oC) Parameter Symbol Ratings Unit Maximum voltage (note2) VMAX 7 V Maximum voltage (note1) VIOMAX 4.5 V Power Dissipation (note3) Pd 1550 mW Operating Temperature Range Topr -40 ~ +85 ℃ Storage Temperature Range Tstg -55 ~ +150 ℃ note1) VIO,RESETB,CE,SDA,SCL,IFMODE,SYNC,CLKIN,CLKOUT,TEST1,TEST2,TEST3,TESTO, DO terminal note2) Except the above note3) 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. ●Operating Conditions (VBAT ≥VIO, VINSW≥VBAT, Ta=-40~85 oC) Parameter Symbol Limits Unit VBAT input voltage VBAT 2.7 ~ 5.5 V VINSW input voltage VINSW 2.7 ~ 5.5 V VIO pin voltage VIO 1.65 ~ 5.5 V |
