Supply Bias voltage input for controller
Digital PWM input control to globally PWM all channels
ANLG input bias signal to globally adjust full scale brightness. (intended for external power derating cir-
cuit for SCA conditions)
Base drive connection for external channel high voltage BJT
Current setting resistor for LED channel (Full Scale Brightness of 1 V)
Open Cathode Anode over−voltage threshold trigger input (sets maximum allowed LED Anode voltage,
1 V trigger)
LED Anode capacitor
Do not connect, leave floating
Internal cathode reference voltage (divided by 2 and buffered to 1.8 V). Intended to provide reference
bias for external circuitry, such as the power derating operational amplifier.
Do not connect, leave floating
Cathode voltage with compensation (divided by 2 and buffered). Leave floating if not used.
Current sink feedback (1 mA max) used with external circuit to control of LED Anode supply voltage
Shorted Cathode−Anode Fault output logic signal (open−drain, active low) indicating presence of excess-
ive cathode voltage
Connect pin to GND
Open Cathode−Anode Fault output logic signal (open−drain, active low) indicating an Open−channel
condition
Lowest LED Cathode sense input (connect to sensing diode anodes)
Highest LED Cathode sense input (connect to external high voltage transistor and zener/diode network)
