L6382D5

Lighting, Ballast Controllers Overview

The L6382D5 is a Power Factor Correction and Ballast Controller designed for microcontrolled electronic ballasts integrating PFC and half-bridge stages. It features four MOSFET driving stages for PFC, half-bridge, and preheating functions, alongside a dedicated Power Management Unit (PMU) with a reference capable of supplying a 5V microcontroller under all conditions. The device operates within a supply voltage range of 14V to 17V and draws a supply current of 2.1 mA. It is housed in a 20-SOIC package with a width of 7.50mm.

Lighting, Ballast Controllers Feature Summary

• Integrates four distinct MOSFET driving stages for PFC, half-bridge, and preheating applications within a single IC.
• Includes a dedicated Power Management Unit (PMU) providing a stable reference to supply the microcontroller in any operating condition.
• Features integrated high-voltage startup and an internal two-point VCC regulator for simplified power management.
• Provides cross-conduction protection via interlocking and over-current protection with a digital output signal.

Lighting, Ballast Controllers Applications

• Microcontrolled electronic ballasts
• LED drivers embedding PFC stages
• Systems requiring integrated half-bridge stage control

Lighting, Ballast Controllers Procurement Notes
