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).
