點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. DM132 DM132 Version ：A.014 Page： DM132 16-Channel PWM-Controlled Constant Current Driver for LED Displays General Description The DM132 is a LED driver incorporating shift registers, data latches, 16-channel constant current circuitry with current value set by an external resistor, 1024 gray level PWM (Pulse Width Modulation) functional unit and time division capability. Each channel can provide a maximum current of 60 mA. Time division operation allows driving up to 1 or 2 LEDs with a single output channel (mode-1 and mode-2 respectively).
Features
˙ Constant current outputs with current value settings by an external resistor ˙ Maximum output current: 60 mA ˙ Time division output allows the drivi ng of 1 or 2 LEDs with a single output ˙ Maximum / minimum output voltage: 20V / 1.1V ˙ 10 bits luminance data with PWM current outputs ˙ Serial shift-in architecture for lumi nance data in time division Mode 1 and Mode 2
