The MIC2291BD5-TR is a PMIC - LED Drivers device by Microchip Technology, ideal for backlighting or general purpose LED Drive applications. It is extremely small and is designed to drive up to 8 LEDs in the most efficient manner possible. With the help of its space-saving package, the MIC2291BD5-TR offers an optimal balance between cost and performance.

The MIC2291BD5-TR is equipped with two main operating modes which make it very efficient when it comes to driving LEDs. The first one is the linear regulator mode, which works by smoothly changing the output current up or down along with the change in the input voltage. This ensures that the LEDs have constant and consistent light quality as the operating voltage changes. The second operating mode is the Pulse Width Modulation (PWM) mode. This mode allows for very precise current control in LED applications, allowing manufacturers to achieve a high degree of brightness control and customization.

The MIC2291BD5-TR also features an on-chip dimming logic, which is used to switch the LED driver between its two operating modes in a controlled manner. With the help of this control logic, the user can easily program the current control of the LED devices. Additionally, it features an adjustable bias voltage which can be used to match the application’s output current needs.

In addition to its operating modes, the MIC2291BD5-TR includes built-in fault protection and open-circuit detection. The fault protection ensures that current faults are detected and immediately corrected to prevent permanent damage of the systems. Similarly, the open-circuit detection is used for detecting open circuits in the circuitry and setting the output current accordingly. Another great feature of the MIC2291BD5-TR is its Over-Voltage Protection which helps in preventing over-voltage stress on the device.

Due to its effectiveness in driving LEDs with high efficiency, the MIC2291BD5-TR is widely being used in a variety of applications and markets. Some of the prominent applications of this device include automotive, automotive lighting, consumer electronic displays, and more. Additionally, it is also being used in the industrial and entertainment markets, including signs and displays.

The MIC2291BD5-TR is an ideal PMIC - LED Drivers device which provides a unique combination of performance, size, cost and features. It implements advanced fault and protection while providing remarkable efficiency and power savings. With its feature set and costs, this device offers a great alternative to conventional LED driving solutions.
