Device description
Designed in High-voltage BCD Off-line technology, the L6382D5 is provided with 4 inputs
pin and a high voltage start-up generator conceived for applications managed by a
microcontroller. It allows the designer to use the same ballast circuit for different lamp
wattage/type by simply changing the
C software.
The digital input pins - able to receive signals up to 400KHz - are connected to level shifters
that provide the control signals to their relevant drivers; in particular the L6382D5 embeds
one driver for the PFC pre-regulator stage, two drivers for the ballast half-bridge stage (High
Voltage, including also the bootstrap function) and the last one to provide supplementary
features like preheating of filaments supplied through isolated filaments in dimmable
applications.
A precise reference voltage (+5V ±2%) able to provide up to 30mA is available to supply the
C in operating mode. Instead, during start-up and save mode the current available at V
REF
is up to 10mA and it is provided by the internal high voltage start-up generator.
The chip has been conceived with advanced power management logic to minimize power
losses and increase the application reliability.
In the half-bridge section, a patented integrated bootstrap section replaces the external
bootstrap diode.
The L6382D5 integrates also a function that regulates the IC supply voltage (without the
need of any external charge pump) and optimizes the current consumption.
