Key Features
– Fault Detection and Management
Circuit (StayLit™):
• A dedicated Pin allows the
module to detect an open/shorted
lamp condition
• In addition when only one of the
two lamps in the LCD fails open,
the second lamp will continue to
operate with a FAULT signal
toggling to indicate the failed
condition.
• Perfect for Industrial/Consumer
Application where continued
SAFE operation is key

Key Features
– Externally Programmable Maximum Output Current (PanelMatch™) = the
customer is able by changing a single settings to regulate the current flowing
through the lamp
• The module can be used for different panels requiring different Lamp Currents
– Easier Supply Chain, Perfect for Distribution
• The customer can purposely drive the lamps at a lower or higher current to
decrease or increase nominal brightness and lamp life
– Application Flexibility
