The MIC2287CBD5-TR is a Power Management IC (PMIC) that is used as an LED driver. It is a monolithic high-voltage, current-mode switching regulator that is specifically designed to drive LEDs in large arrays. The device can take an input voltage up to 36V and operate in an adjustable output current up to 1A.

This device provides excellent LED current accuracy by using a 0.3 ohm sensing resistor. The output current is also adjustable using an external resistor. It also has a PWCEN pin which can be used to disable the device when its driver requirements are not met. This pin will allow the system to maximize efficiency and reduce heat dissipation.

The MIC2287CBD5-TR also provides protection against open circuit and short circuit conditions. It will shut down if the LED current exceeds the maximum allowed or if the LED load is disconnected. This will ensure the safety of the system and keep it from being damaged.

In addition to this, the IC includes a hysteresis comparator and thermal shutdown protection. This allows it to detect any changes in the LED current, ensuring that the LED array remains stable and safe. Furthermore, it can also detect over temperature conditions and protect the device from damage.

Furthermore, this device has a low on-resistance MOSFET that has a low feedback voltage threshold. This allows for a higher switching frequency, reducing power loss and heat dissipation. It also allows for the device to achieve high efficiency, extending the life of the LEDs.

Finally, this device also supports a wide range of input and output voltage options. This allows it to be used in a variety of applications, including low-voltage DC/DC converters, LED signboards and stage lighting.

In conclusion, the MIC2287CBD5-TR is an ideal choice for various LED driver applications. It provides outstanding performance, high efficiency, and robust protection features.
