PRODUCT 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).
