Integrating a PMIC - LED Driver solution into existing controllers or single chip solutions can be a challenge as they can be too large and power hungry. MIC2843AYMT-TR is a perfect solution to this problem as it is a small, low power PMIC - LED driver with integrated active balancing, narrow voltage and current range for versatility. The MIC2843AYMT-TR features an input voltage range of 5V to 30V, a current range from 10mA to 1.5A and an internal shutdown. It has excellent regulation accuracy, well balanced current alignment, programmable brightness and significant protection features with built in overvoltage, overtemperature and overcurrent protection.

The MIC2843AYMT-TR is a member of the MIC2843 family of high efficiency, low voltage, low current PMIC - LED drivers. The device has four parallel channels, each with an independent power control and overcurrent protection. The MIC2843AYMT-TR has a wide input voltage range, allowing it to operate from low voltage supplies, as well as battery power sources. Its external feedback connection allows it to be easily dimmed or brightened, while its four independent current outputs provide flexibility and accuracy.

The MIC2843AYMT-TR is suitable for high temperature environments, as it has an operating temperature range of -40°C to +105°C. It has a maximum quiescent current of 7.5μA. The device also features low RDS(on) MOSFETs in its output stages, offering both high efficiency and minimal current losses. This reduces overall power dissipation and supports long battery life.

The architecture of the MIC2843AYMT-TR is designed to maximize efficiency in battery-powered or power sensitive applications. The onboard active balancing function allows for four channels to be balanced simultaneously, resulting in a more uniform current output across the LEDs. The MIC2843AYMT-TR also features programmable brightness levels for each of the four channels.

The MIC2843AYMT-TR is designed to reduce the number of external components needed for the power supply circuit and minimize system costs. It has a wide input voltage range, allowing it to operate from both AC and DC power sources. The device also features built-in soft start and input current limiting, reducing the required gate drive losses and increasing power efficiency. In addition, its PCB routing is optimized for space saving, improving circuit robustness and reducing EMI.

The MIC2843AYMT-TR is a robust and reliable LED driver that is suitable for off-line or battery powered applications. With its four independent channels and active balancing, it is a great solution for LED lighting applications that require a low-cost, low-power LED driver. The device also offers robust protection features, such as overvoltage, overtemperature, and overcurrent protection, to protect against system failure.
