Lamp Brightness Control. An analog voltage at this input controls the lamp brightness. See
Table 1 for details.
Supply Voltage Monitor. The DC inverter supply voltage is monitored by an external resistor
divider. The resistor-divider should be set such that it provides 2V at this pin for the minimum
allowable range of the DC inverter supply. Pulling this input below 2V will turn the lamps off and
reset the controller. Connect to V
MOSFET Gate Drive A for Channel 1. Connect directly to the gate of a logic-level mode
n-channel MOSFET.
MOSFET Gate Drive B for Channel 1. Connect directly to the gate of a logic-level mode
n-channel MOSFET.
Lamp Current Monitor Input for Channel 1. Lamp current is monitored by a resistor placed in
series with the low-voltage side of the lamp.
Over Voltage Detection for Channel 1. Lamp voltage is monitored by a capacitor divider
placed on the high-voltage side of the lamp.
