MOSFET A Gate Drive. Connect directly to logic-level mode n-channel MOSFET. Leave open if channel
is unused.
MOSFET B Gate Drive. Connect directly to logic-level mode n-channel MOSFET. Leave open if channel
is unused.
Lamp Current Monitor Input. Lamp current is monitored by a resistor placed in series with the low-voltage
side of the lamp. Leave open if channel is unused.
Overvoltage Detection. Lamp voltage is monitored by a capacitor divider placed on the high-voltage side
of the transformer. Leave open if channel is unused.
Active-Low Fault Output. This open-drain pin requires external pullup resistor to realize high logic levels.

Lamp Frequency Input/Output. This pin is the input for an externally sourced lamp frequency
when the DS3882 is configured as a lamp frequency receiver. If the DS3882 is configured as a lamp
frequency source (i.e., the lamp frequency is generated internally), the frequency is output on this pin for
use by other lamp frequency receiver DS3882s.
Lamp Oscillator Resistor Adjust. A resistor to ground on this pin sets the frequency of the internal lamp
oscillator.
Analog Brightness Control Input. Used to control the DPWM dimming feature. Ground if unused.
DPWM Input/Output. This pin is the input for an externally generated DPWM signal when the
DS3882 is configured as a DPWM receiver. If the DS3882 is configured as a DPWM source (i.e., the
DPWM signal is generated internally), the DPWM signal is output on this pin for use by other DPWM
receiver DS3882s.
