CAT310
LED Driver, 10-Channel
Description
The CAT310 is a 10channel LED driver for automotive and other
lighting applications. All LED output channels are driven from a low
onresistance opendrain High Voltage CMOS NchFETs 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 multicolor
instrumentation displays.
A highspeed 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 daisychain devices in
large cluster LED applications.
During initial power up all channels are reset and cleared via an
undervoltage lock out (UVLO) detector and for added protection all
channels are disabled in the event of a battery overvoltage condition
(19 volts or more).
