Sensing the current for controlling the electricity is a key element in many applications. This article will focus on IRS2982STRPBF, which belongs to PMIC-LED Drivers, to discuss its application field and working principle. IRS2982STRPBF is a low voltage driver that consists of three IGBTs and six power MOSFETs. It is designed to control the current, voltage and power of LEDs with a variety of features, including dimming and intensity modulation, higher efficiency and smaller size.

In general, IRS2982STRPBF has great application fields such as lighting, sensor, signal etc. For example, in lighting applications, IRS2982STRPBF can be used to drive any kind of LED, and its dimming, intensity modulation and high efficiency features make it an ideal choice. Furthermore, owing to its low voltage operation, it is also suitable for use in signal application and sensors that require a short-time, current pulses.

The working principle of IRS2982STRPBF is extremely simple. The device consists of two integrated power stages: the high voltage side and the low voltage side. On the high voltage side, two IGBTs, or insulated gate bipolar transistors, are used to switch the current from the high voltage supply to the LEDs. On the low voltage side, four power MOSFETs are connected in series, forming a half-bridge. This half-bridge works as a high current switch and can provide up to 4A of current to the LEDs. Additionally, two power MOSFETs are used to provide a reverse voltage protection that prevents any high voltage from flowing towards the LEDs.

Overall, IRS2982STRPBF is an ideal device for driving LEDs efficiently and with a variety of features. Its wide application field and simple operating principle make it suitable for a large range of lighting, signal and sensor applications.
