CAT310

10 Channel Automotive LED

Display Driver

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).
