The CAT310 is a 10-channel LED driver for automotive and other lighting applications. All LED output channels are driven from a low on-resistance open-drain High Voltage CMOS Nch-FETs and are fully compliant with "Load Dump" transients of up to 40 volts. The LED bias current of each channel can be set independently using an external series ballast resistor, making the device ideal for multi-color instrumentation displays.
