The L6382D is a specifically designed product by STMicroelectronics that functions either as a two-channel constant current power supply or as a dimmable, dual driver dimmable lighting ballast. It is a device that can be used in a variety of lighting- and ballast-relating applications. This article will discuss the various application fields of the L6382D and its integrated working principle in detail.

Overview of the L6382D

The STMicroelectronics L6382D is essentially an integrated circuit that functions as a pole current driver and as a lighting controller. It is designed with an integrated dual-channel power switch for a wide variety of lighting- and ballast-related applications including LED drivers, LED screens, LED stripes, LED lamps, LED bulb arrays, LED modules and LED strips. The device is fabricated using the ST-DMD – a 0.18µm high-voltage process technology that supports several high voltage, low-voltage and logic functions. It also has built-in analog and digital sensors, transistors, drivers and integrated circuits.

Application fields and use cases of the L6382D

The L6382D can be used for a variety of application fields that require a constant current power supply or lighting ballast controllers to operate. The device’s dual-channel power switch allows for easy power conversion from AC to DC which is essential for applications that utilize either EV’s or HID lighting systems. This device can be used to control and monitor the current flowing through LED light sources such as LED lamps, LED strips, LED drivers and LED modules. Additionally, this device can be used to provide energy-saving dimming control and power-efficient lighting programs. It can also be used to regulate the luminance of LED lighting fixtures, RGB LED lighting fixtures and LED displays.

Furthermore, the L6382D can be used as a ballast controller as it supports 0-10V and/or 1-10V analog dimming control of various lighting platforms. It has a built-in phase-angle dimming control that can be used to control either DC or AC lighting and a current sensing circuit that can be used to prevent over-voltage and over-current situations when working with inductive loads such as CFL and HID lights.

Working principle of the L6382D

As previously mentioned, the L6382D is an integrated circuit that functions as a pole current driver and as a lighting controller. The device is designed with an integrated high voltage switching MOSFET that is specifically designed for driving current through poles or wires. The MOSFET has two channels, with each channel capable of controlling different poles or wires. The device is operated by applying the control signals to the DACOUT, which then can either control the digital-to-analog converter (DAC) or the digital-to-analog switch (DAS). Depending on the application, either digital signals or analog signals can be used to control the poles or wires.

In terms of lighting control, this integrated device is capable of regulating luminance by controlling the output current of the power switch. The device also supports 0-10V and/or 1-10V analog dimming control for a variety of lighting platforms. It also has a current sensing circuit that can be used to prevent over-voltage and over-current conditions when working with inductive loads. The L6382D also supports a wide range of features including electronic overtemperature protection (OTP), dimming detection, and dimming feedback.
