AL5812FF-7 is a PMIC –LED driver designed to help control the brightness of modern lighting applications such as LCD backlights, keypads and other dimmable light sources. It features on-die voltage regulation and over-current protection as well as current-sense comparator in order to ensure superior performance and operational stability.

In terms of application field, AL5812FF-7 mainly caters to Mobile phone, Tablet PC, TV set, Monitor and other consumer electronics products. Each type of electronics requires different level of power and current supply, and this PMIC –LED driver has the ability to execute all of them with great precision. Furthermore, to meet the new requirement of bi-color backlight and PWM dimming, AL5812FF-7 has the necessary feature to combine two different channels’ output current.

The working principle of AL5812FF-7 is based on a principle of using an integrated chip to accurately and reliably drive a power MOSFET. It consists of an on-die voltage regulator, an output current reference and measurement, over-current protection and current-sense comparator. The voltage regulator is used to keep the output voltage in regulation and to prevent over voltage or under voltage conditions which can damage the connected LEDs. The output current reference is then used to accurately control the LED brightness level, and the over-current protection and current-sense comparator is designed to cut off the supply current when the current goes beyond the set limit, thus protecting the connected LEDs from being damaged.

In short, AL5812FF-7 is a great solution for those looking to accurately and reliably control the brightness of lighting applications with great precision. It is easy to use and has built-in features such as on-die voltage regulation, over-current protection and current-sense comparator to ensure superior performance and operational stability.
