The MAX16804ATP+T PMIC (Power Management IC) provides a fully integrated LED controller for driving up to four independent strings of LEDs. The device features an Ultra-Low quiescent current, adjustable operating current using integrated high-resolution current-setting DACs, independent channel control, a compact 6-by-6 mm footprint, easy-to-use control and configuration registers, an oscillator, and a comprehensive diagnostic load Fault protection system. The device also provides integration of multiple LED drivers, a single I2C bus interface, simultaneous LED brightness control, a Daisy Chain capability, and thermal foldback protection.

It can be used in a variety of lighting configurations, including those with up to four different LED strings, each with up to 30 different colors. This can be applied in automotive headlight, controller, lighting and interior illumination systems. It can also be used for street and industrial lighting, as well as large display systems, including those requiring multiple colors. Furthermore, the device is suitable for applications that require small size, low power control, and high driving accuracy.

The MAX16804ATP+T utilizes an array of configurable DACs to control the current through each of the four independent LEDs. Through the integrated high resolution DACs, the current can be adjusted with a resolution of 1/256 of the total current rating. The I2C interface allows complete control of the four LED strings, allowing the user to program the current level, dimming levels, and color channel mode. In addition, the device also includes a built-in 16.8 kHz oscillator, allowing the system to be integrated into existing networks without the need of an external device. The device also features a comprehensive diagnostic protection system, providing a variety of safety features and protections including overcurrent, overtemperature, and open-drain faults.

The MAX16804ATP+T also includes an optional Daisy Chain mode that allows multiple devices to be connected in a serial fashion. By grouping multiple devices, the control and resolution of the LEDs can be improved by setting the individual Resistance and voltage levels of each LED. This can be used for applications requiring a wide variety of colors and brightness levels.

Overall, the MAX16804ATP+T provides a small size, low power, and high accuracy LED controlling solution for a wide range of LED lighting configurations. It has a fully integrated LED controller for up to four independent LED strings, adjustable current settings, integrated diagnostic protection, a 16.8kHz oscillator, and an optional Daisy Chain mode. It can be used in automotive, industrial and display lighting applications, enabling more efficient and complex lighting solutions.
