Introduction

MIC3289-16YML-TR is a LED driver integrated circuit designed for power management applications. It is a PMIC specialty chip used to drive LED devices and is specifically designed to support a variety of LED driver applications. The product provides features such as wide input voltage range, excellent electrical performance, exceptionally tight output accuracy, and a low standby current.

Application Field

MIC3289-16YML-TR can be used in general lighting applications including LED street lights, LED downlights, LED bay lights and LED panel lights. It has a wide input voltage range that supports operation from AC mains supply, and the device can be used to drive from one to up to 16 LEDs in series. In addition, the device can be used for applications such as home appliance lighting, commercial lighting, billboard advertising, and automotive lighting.

The device provides a very efficient driver solution which can reduce system costs by eliminating the need for an additional driver IC or transformer. In addition, the device can provide a good thermal design with its integrated thermal protection function and surge suppression function. Finally, the device also features a low shutdown current consumption, enabling a very low standby power consumption.

Working Principle

MIC3289-16YML-TR features several internal circuits which allow it to drive LEDs in various combinations and with different duty cycles. Its main internal components include an EN logic circuit, an LED driver circuit, and a low voltage microcontroller. The EN logic circuit controls the overall operation of the device, providing the basic on/off control of the LED drivers. The LED driver circuit is a power switching circuit which controls the current that is applied to the LEDs, allowing them to be driven at different levels of brightness. Finally, the low voltage microcontroller is used to preset the EN logic and LED driver circuits, allowing them to operate in the desired manner.

The device can operate in a wide range of different modes such as PWM mode and ON/OFF mode. In PWM mode, the LED drivers are driven by a pulse-width modulation signal, allowing them to be dimmed or brightened depending on the duty cycle of the signal. In ON/OFF mode, the LED drivers are driven only when there is a logic high signal applied to the EN logic circuit, allowing them to be turned on or off as needed.

The device also features several protection functions to ensure safe operation of the LEDs. It features an over-voltage protection circuit, over-temperature protection circuit, and a short-circuit protection circuit. The over-voltage protection ensures that the LEDs are not driven with too much current while the over-temperature protection prevents the LEDs from being driven too hot. Finally, the short-circuit protection circuit prevents the LEDs from being damaged in the event of a sudden short-circuit.
