LED Outputs - Group B
Enable for Group-A LEDs (current outputs). Logic input.
High = Group-A LEDs ON. Low = Group A LEDs OFF.
Pulsing this pin with a PWM signal (100Hz-1kHz) can be used to dim LEDs.
Enable for Group-B LEDs (current outputs). Logic input.
High = Group-B LEDs ON. Low = Group B LEDs OFF.
Pulsing this pin with a PWM signal (100Hz-1kHz) can be used to dim LEDs.
Placing a resistor (R
SETA
) between this pin and GND sets the LED current for
Group A LEDs. LED Current = 100 x (1.25V ÷ R
SETA
).
Placing a resistor (R
SETB
) between this pin and GND sets the LED current for
Group B LEDs. LED Current = 100 x (1.25V ÷ R
SETB
).
