Application Information
The ERG SFD2EB4016F has been designed to be configured in multiple ways:
NO DIMMING
•OPERATION: The SFD2E can be configured to operate without dimming by floating the Control (J1-8) pin.
•Pins 1, 2 and 3 of connector J1 must be connected to +Vin, between 10.8 and 18 Vdc. Pins 4, 5 and 6 of
connector J1 must be connected to GND.
•Enable Pin (J1-7) must be high for the driver to be on.
ONBOARD PWM DIMMING
•OPERATION: Onboard PWM configuration as shown in Figure 1 allows the user to control display brightness by
controlling the onboard PWM generator. The user is responsible to provide an analog control signal. A minimum
pulse width of 80μs is possible with this configuration.
•DIMMING: Dimming is accomplished by applying an analog voltage to the Control Pin (J1-8). Display brightness
is modulated by controlling the Control Pin voltage as shown in Graph 1.
•ENABLE/DISABLE: The driver may be enabled or disabled (turned on and off) by applying a DC voltage to the
Enable Pin(J1-7). Enable Pin on and off levels are specified in the Operating Characteristics section of the data
sheet.
• Pins 1, 2 and 3 of connector J1 must be connected to +Vin, between 10.8 and 18 Vdc. Pins 4, 5 and 6 of
connector J1 must be connected to GND.
EXTERNAL PWM DIMMING
•OPERATION: External PWM configuration as shown in Figure 2 allows the user to control display brightness
with an externally generated PWM signal. The user is responsible to provide the PWM signal. A minimum pulse
width of 80μs is possible with this configuration.
•DIMMING: Dimming is accomplished by applying a PWM signal to the Enable Pin (J1-7). Enable on and off
levels are specified in the Operating Characteristics section of the data sheet. Display brightness is modulated
by controlling the PWM duty cycle as shown in Graph 2.
•Pins 1 through 3 of connector J1 must be connected to +Vin, between 10.8 and 18 Vdc. Pins 4 through 6 of
connector J1 must be connected to GND.
