The BD6581GU-E2 is a high performance, chip-on-board (COB) LED driver product belonging to the Power Management Integrated Circuit (PMIC) family of devices. It is a one-channel, step-down constant current driver specifically designed for direct driving of LEDs in automotive and general lighting applications.

The BD6581GU-E2 is capable of driving up to 2 LEDs at a maximum current of 1.5A and a minimum current of 250mA. It offers both MPT and ZPT dimming options, and supports a wide range of dimming methods including PWM, power, time and temperature-dependent dimming. It also comes with a built-in over-temperature and under-voltage protection. The device\'s wide operating range allows for LED lamps and luminaires to operate in almost any environment.

The BD6581GU-E2 is manufactured using RoHS-compliant materials and is available in fourteen different packages ranging from 0.3mm to 2.3mm in height and 0.3mm to 2.6mm in width. It is also compatible with a wide range of boost, buck and PFC controllers, providing a high performance and reliable solution for power management.

The BD6581GU-E2 is designed to provide constant current output for driving LEDs in automotive and general lighting applications. The device adopts a proprietary current setting methodology based on a high precision trimming resistor and advanced pulse width-modulation (PWM) control. An internal slope compensation algorithm ensures a smooth transition from dimming levels to prevent flickering, while external frequency programming and amplitude scaling allows for fine tuning of the LED driving current and dimming levels.

In addition to its excellent completeness, the BD6581GU-E2 also features various protection functions. It provides over-temperature protection (OTP) and an adjustable under-voltage lockout (UVLO) to protect against high and low voltage conditions. The device also incorporates an error flag output to indicate LED open or open-circuit faults.

The BD6581GU-E2 is a high performance and reliable LED driving solution suitable for a variety of lighting applications. Its wide range of options and protection features make it an ideal choice for automotive and general lighting applications.
