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).
