PMIC - LED Drivers are devices that convert electrical power into light. The MP3387LGRT-P is a 4-channel Power Management Integrated Circuit (PMIC) that is specifically designed for driving LEDs. The MP3387LGRT-P has several features that make it ideal for applications including Low Voltage (Voltage, up to 1.5V) and High Current ( current up to 10A) applications.

The MP3387LGRT-P offers several significant benefits for LED-driving applications. It utilizes a 4-Channel Pulse Width Modulation (PWM) dimming circuit in order to provide dimming control and brightness, from 30%-100%. It also provides reverse-polarity protection and over-voltage protection, as well as current-sensing and thermal shutdown protection. The MP3387LGRT-P also offers a high switching frequency (up to 500kHz) and low side and high-side Integrated MOSFETs for improved linearity and avoidance of switching errors.

The MP3387LGRT-P is well-suited for both indoor and outdoor LED lighting applications, such as vehicle lighting, street lighting and park or garden lighting. The 4-channel capability of the MP3387LGRT-P allows it to drive several LED’s in series or parallel configurations. This allows it to be used in a wide variety of applications, from simple to more complicated ones.

The MP3387LGRT-P works by pumping power from its internal power supply, through the 4 channels and through the LEDs. The internal power supply is adjustable and can be set in the range of 0.7V to 1.5V. It has four external pins that are used to control the voltage and current setting of each of the channels. This enables the design to be easily customized to meet the individual needs of the application.

The MP3387LGRT-P also includes a 4-channel 16-bit Pulse-Width Modulation (PMW) dimming circuit in order to provide a precision dimming range from 30%-100%. The dimming circuit is fully adjustable and can be configured to various frequency levels, ranging from 10 Hz to 1kHz. Additionally, the PWM circuit provides reverse polarity protection, current-sensing protection, and thermal shutdown protection. This ensures that the MP3387LGRT-P is safe to use in applications with potentially high-energy sources.

In addition to the PMW dimming circuit, the MP3387LGRT-P also has an adjustable high-side and adjustable low-side Integrated MOSFETs. This provides efficient and precise current control and improved linearity, by avoiding switching errors. The MP3387LGRT-P also has an adjustable switch-mode frequency, which can be set between 100KHz and 500KHz, to meet the requirements of different applications.

Overall, the MP3387LGRT-P is an ideal device for LED lighting applications. It is simple to install and use, and it offers a range of features that make it well-suited for various applications, including residential, commercial and industrial uses. It has several safety features, including reverse polarity protection, current-sensing protection, and thermal shutdown protection. The MP3387LGRT-P is also easy to configure, with adjustable voltage and current settings, adjustable PWM frequency, and adjustable high-side and low-side Integrated MOSFETs.
