CAT4026  
6-Channel LED Controller  
with Fault Diagnostics for  
Large Panel LED  
Backlighting  
http://onsemi.com  
Description  
The CAT4026 is a high performance, large panel LED controller  
designed to control six constant current high voltage LED strings.  
Added control circuitry monitors the lowest cathode voltage and  
generates a feedback control signal to an external Switch Mode Power  
Supply (SMPS) to provide a low cost and efficient solution for large  
panel high voltage LED backlighting.  
SOIC28  
V SUFFIX  
Each LED channel current is accurately matched and controlled by  
sensing an external resistor in series with a low cost bipolar power  
transistor. This allows current and heat dissipation concerns to be  
mitigated from the CAT4026 device package.  
For added system reliability, both OpenCathodeAnode (OCA)  
and ShortedCathodeAnode (SCA) fault detection circuitry has been  
included along with independent Fault flag logic outputs for  
diagnostic purposes.  
LED current dimming in all six channels can be precisely controlled  
by either a Pulse Width Modulation signal via the PWM input pin or  
by an analog dimming voltage applied at the ANLG pin. In addition  
the ANLG pin provides a convenient method for limiting the overall  
maximum power dissipation in the event of excessive LED shorting  
within any LED string.

The device will automatically enter low current shutdown mode by  
taking the PWM pin low for an extended length of time.
