The NCL30086BHDR2G is an LED driver that is part of the PMIC, or Power Management Integrated Circuit, series of integrated circuits. It is designed to provide efficient and reliable LED lighting solutions for a variety of applications, from automotive and industrial applications to consumer electronic products. The device is powered by a single power supply, typically 5.0V to 12.0V, and is capable of driving up to six LEDs in series. The NCL30086BHDR2G is designed to provide constant-current regulation of up to 700 mA, eliminating the need for external current limiting resistors and providing excellent lighting uniformity for LEDs.

The NCL30086BHDR2G provides a wide range of operating modes and features. The device is adjustable with a single resistor across the Enable pin and offers three operating modes: constant-current, adjustable current, and dimmable. In the constant-current mode, the device provides a regulated current that is independent of LED forward voltage and temperature variations, allowing for accurate and consistent LED modulation. The adjustable current mode provides control of the LED current over a wide range, allowing the device to be used in applications where higher or lower current outputs are needed. The dimmable mode allows the device to be used in applications where dimming control is required, such as LCD backlighting.

The NCL30086BHDR2G has several other features that help ensure reliable operation. The device contains an over-temperature protection circuit that limits its output current when the die temperature exceeds a certain limit. A reverse current blocking diode and an IDDQ monitoring circuit protect the device from reverse current and device failure by monitoring its IDDQ, or current drawn when the device is in shutdown. The device also features an Active PWM dimming mode, allowing selection of different levels of brightness by controlling the dimming frequency. Finally, the device includes a soft-start feature that prevents inrush currents caused by sudden changes in LED voltages.

In summary, the NCL30086BHDR2G LED driver is an ideal solution for a wide range of LED lighting applications. It offers excellent efficiency, reliable operation, and adjustable current and dimming capabilities, making it a versatile and cost-effective LED driver solution. With its wide range of features and low profile, the device is the perfect choice for automotive, industrial, and consumer electronic applications.
