Description
The L6382D is suitable for microcontrolled
electronic ballasts embedding a PFC stage and a
half-bridge stage. The L6382D includes 4
MOSFET driving stages (for the PFC, for the half
bridge, for the preheating MOSFET) plus a power
management unit (PMU) featuring also a
reference able to supply the microcontroller in any
condition.
Besides increasing the application efficiency, the
L6382D reduces the bill of materials because
different tasks (regarding drivers and power
management) are performed by a single IC, which
improves the application reliability.

Supply section µPUVLO (µPower Under Voltage Lock Out): This block controls the power ● management of the L6382D ensuring the right current consumption in each operating state, the correct V up generator switching.

... The DIM (Digital Input Monitor) block manages the input signals delivered to the drivers ensuring that they are low during the described start-up procedure; the DIM block controls the L6382D behaviour during both save and operating modes. When the voltage on pin CSI overcomes the internal reference of 0.5V (typ.) the block latches the fault condition: in this state the OCP block forces low both HSG and LSG signals while CSO will be forced high ...
