CAT310 LED Driver, 10-Channel Description 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. A high−speed serial interface (.

CAT310 LED Driver, 10-Channel Description 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. A high−speed serial interface (suitable with both 3.3 volt and 5 volt systems) feeding a 10 bit shift register is used to program the desired state (on/off) of each channel. The device offers a blanking control pin (BLANK) which can be used to disable all channels on demand. A serial output data pin (SOUT) is provided to daisy−chain devices in large cluster LED applications. During initial power up all channels are reset and cleared via an under−voltage lock out (UVLO) detector and for added protection all channels are disabled in the event of a battery over−voltage condition (19 volts or more).
