Description

The L6382D5 is suitable for microcontrolled electronic ballasts embedding a PFC stage and a half-bridge stage. The L6382D5 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.

Features

■ Integrated high-voltage start-up

■ 4 drivers for PFC, half-bridge & pre-heating MOSFETs

■ Fully integrated power management for all operating modes

■ 5V microcontroller compatible

■ Internal two point VCC regulator

■ Over-current protection with digital output signal

■ Cross-conduction protection (interlocking)

■ Under voltage lock-out

■ Integrated bootstrap diode

Applications

■ Dimmable / non-dimmable ballast
