BCM5825A1KPBG is a light-emitting diode (LED) visible source controller chip. It can also serve as a white LED dimmer, a low-current LED driver, a dynamic driving mode, and various other light source control applications. First introduced in 2019, it was designed by Broadcom Corp. as a high-performance controller for LED lighting systems.

The device has a small 2.5x2.5 mm package and a low current consumption, which makes it the perfect choice for LED applications in mobile and low-power consumer devices. It also offers excellent dimming control and low noise performance. Furthermore, it features a wide range of digitally programmable dimming functions.

The chip can be used to control a variety of light sources from miniature incandescent lamps to powerful high-intensity white LEDs. The device is capable of driving up to 20mA of LED current per channel. This makes it ideal for applications such as LED dimming, flash-light control, and optical communication.

The BCM5825A1KPBG operates using pulse width modulation (PWM) with eight adjustable duty cycles. It has a wide open-circuit voltage range from -0.5V to 6V and adjustable frequency from 10kHz to 500kHz. The device is capable of controlling up to four independent, parallel circuits for continuous dimming up to 100%. This allows designers to create highly programmable lighting designs with minimal cost.

In addition to the above features, the device also has excellent thermal performance and low profile, low standby current features. The device is also well-suited for applications such as automotive application and lighting design, where efficiency and cost-effectiveness are two of the top factors.

To further expand the capabilities of the BCM5825A1KPBG, it can be combined with other components such as LED drivers or temperature sensors. For example, when a temperature sensor is used with the chip, it is possible to precisely control LED brightness and temperature. This can be done to create high-efficiency LEDs that are tolerant to temperature variations.

The BCM5825A1KPBG is a very versatile and powerful light source control device. It offers high performance, low power consumption, and integrated dimming options, making it an ideal choice for a variety of light source control applications. Its digital programming capabilities and ability to control multiple lighting functions make it an attractive device for engineers and designers alike.
