The MP24893DJ-LF-P is an Integrated LED Controller from Monolithic Power Systems. This device is a part of their MP24893 family of LED drivers which have been developed as all-in-one, compact solutions for driving LED’s. Specifically, this LED Driver is suited for LED-lighting applications that require just one LED Controller and one LED Driver to power multiple LED strings.

Application Field

This LED driver is suitable for the following application scenarios: Automotive, Home and Professional Lighting, Interior, Portable and Mobile Lighting. Additionally, the MP24893DJ-LF-P is compliant with the AEC-Q101 Qualified and PPAP Capable Product program and can be used in many applications requiring strict compliance with these standards.

Working Principle

The MP24893DJ-LF-P utilizes a buck-boost topology for driving LEDs, and provides high-side, constant current accuracy and low dropout over a wide input voltage range. The device is designed to accept a wide input voltage range from 4.5V to 40V, and is capable of driving up to 6 strings of LEDs, including the serially connected white LEDs for the backlight LCD monitors.
The MP24893DJ-LF-P contains an on-board Coulomb-counter and a unique dimming feature which allows the customer to program a light intensity - thereby offering a comfortable lighting environment. It also features a constant voltage PWM dimming with a frequency of 500 Hz which reduces flicker often associated with induction or low-voltage dimming systems. It also features a shutdown mode, allowing the customer to power-down the device while keeping data intact.
The MP24893DJ-LF-P is capable of achieving high efficiency with low standby current, reducing the overall power consumption. It also features an over-temperature protection (OTP) circuit which shuts down the LED controller when the temperature at the chip exceeds a certain level. This helps in preventing damage caused by prolonged exposure to high temperatures.
The MP24893DJ-LF-P also comes equipped with integrated under-voltage lockout protection (UVLO). When the input voltage dips below the UVLO threshold level, the device is automatically disabled and the output is turned off. Additionally, the device also features a power-good signal and a reset pin, which can be used to enable/disable the device or reset it respectively.
In conclusion, the Monolithic Power Systems MP24893DJ-LF-P is an easy-to-use and cost-effective integrated LED controller designed for lighting applications requiring precision control, high efficiency and a wide input voltage range. Its wide range of features such as a constant-current control, PWM dimming, over-temperature protection, under-voltage lockout protection, and a power-good signal ensures that it can meet the needs of a variety of lighting applications.
