The MAX16813ATP/V+T is typically classified as a PMIC, or “power management IC,” and is often used as a LED driver. It is designed to regulate the power provided to an LED, as well as to oversee current and temperature control. This device is designed to offer high efficiency, low cost, and low current consumption and can be used both for standard and high-power LEDs.

Application

The MAX16813ATP/V+T is typically used in applications where high voltage and power are needed, such as automotive lighting, industrial equipment, consumer electronics, and general purpose lighting systems. It is also suitable for applications that require high efficiency, such as in DC/DC converters and battery-powered devices. The capability to provide a constant current and temperature control makes it ideal for applications with extremely high power requirements.

Functionalities

The MAX16813ATP/V+T LED drivers are able to provide a constant output current, regardless of supply voltage variation. This is achieved by combining an adjustable shunt regulator with a microcontroller-based regulator loop. This means that it can be used to provide a constant voltage, current, or temperature controlled output. Its integrated current sharing feature helps deliver a consistent current to multiple LEDs connected in series.

Working Principle

The MAX16813ATP/V+T LED drivers use a microcontroller-based regulator loop to control the power provided to an LED. The basic operation of this device is as follows: the microcontroller measures the input supply voltage and calculates the required output current. The current sense circuit then monitors the current being supplied to the LED, and the regulator loop adjusts the output current accordingly. The thermal loop monitors the temperature of the device, making sure that it does not become too hot. If the temperature exceeds a certain threshold, the microcontroller will reduce the output current, preventing the device from becoming damaged.

Conclusion

The MAX16813ATP/V+T is a versatile and efficient LED driver that can be used in a variety of applications. It has the ability to provide a constant voltage, current, or temperature controlled output, making it suitable for applications with extremely high power requirements. The integrated current sharing feature also makes it ideal for applications which require multiple LEDs in series. All of these features make the MAX16813ATP/V+T an attractive choice for many power management applications.
