MIC2289-15BML-TR

The MIC2289-15BML-TR is a CMOS high-brightness LED driver and belongs to Power Management Integrated Circuit (PMIC - LED Driver) category. This device is capable of providing up to 1.5 A of continuous output current with a maximum output voltage of 300 V. The MIC2289-15BML-TR has two driver channels, each with its own separate input, output, and control pins. The two driver channels can be independently controlled or synchronized for multi-channel displays.

The MIC2289-15BML-TR is designed to drive and control HIGH BRIGHTNESS LEDs at regulated currents from 10 mA to 1.5 A. It provides LED dimming and color control flexibility, allowing multiple LED channels to be independently dimmed. The MIC2289-15BML-TR contains a shutdown, logic level clock input, programmable current sink, and a soft-start circuit that allows for smooth LED fade-in and fade-out.

The MIC2289-15BML-TR supports an amplified light feedback loop (ALFL) interface that allows it to drive LEDs in either a linear mode or a saturated mode with a capacitive voltage divider. The ALFL interface can be used to create complex LED dimming profiles, as well as color and brightness effects. The MIC2289-15BML-TR also includes Auto Dimming based on ambient light, as well as a delayed sleep-mode to reduce average current draw.

The MIC2289-15BML-TR can be used to drive automotive interior and exterior lighting, as well as complex industrial displays. The automatic dimming feature is especially useful in a variety of applications including car headlights, exterior displays, or illuminated signs. The ALFL interface allows for sophisticated LED lighting effects that can be dynamically created to meet the needs of the application.

In order to function properly, the MIC2289-15BML-TR needs a power supply voltage of 3.3V to 3.6V. The input to the device is a PWM signal, and the output is a regulated current that is proportional to the duty cycle of the input signal. The device also contains a control pin used to adjust the current sink to control the brightness of the LEDs. The MIC2289-15BML-TR also features a logic level clock input, allowing for synchronized dimming of multiple LED channels.

The MIC2289-15BML-TR is a highly versatile LED driver that can be used in a variety of applications. Its ALFL interface and dimming capabilities make it ideal for automotive and industrial applications. It is a great choice for both cost-sensitive and complex lighting projects.
