HV9985K6-G is a PMIC - LED Drivers integrated power management IC (PMIC) specifically designed to drive high power LEDs while maximizing power efficiency and performance. It is a reliable, low-cost solution that provides optimized output, current regulation and very accurate tracking of inputs and outputs. The device is suitable for automotive and general lighting applications.

The HV9985K6-G has integrated high and low side current sense amplifiers with voltage references, and wide output voltage range control to precisely regulate the LED current, reduce power dissipation, and improve LED current accuracy while maintaining low profile and cost.

Its operating principle is simple and efficient. The device is based on a switching regulator, which is turned on and off by the high-side driver. When the device is turned on, current flows into the LED, and when the device is switched off, all current is blocked from the LED.

The HV9985K6-G is based on a Pulse Width Modulation (PWM) topology, where the output voltage is modulated by adjusting the duty cycle of the switching regulator. This enables precise current regulation of the LED, as well as efficient and accurate tracking of the desired output current. Additionally, the device allows precise control of the LED forward voltage, which can be adjusted to best fit a given LED type and its operating temperature.

The device provides extensive built-in protection against current overloads and overvoltage, improving system reliability and overall lifetime. It also includes comprehensive soft-start capability and a fault detection output, enabling simple diagnostics. Furthermore, the device has built-in current protection mechanism, which allows it to protect the connected LEDs up to 15.6A.

The HV9985K6-G is extremely versatile, featuring a wide operating temperature range of -40°C to +125°C, making it well-suited for automotive and general lighting applications. It also has a wide input voltage range from 8 V to 60 V and is rated for 8x output current. The device is capable of delivering up to 160 W of LED drive power, making it extremely power efficient.

The HV9985K6-G is a reliable, cost-effective solution for driving high power LEDs. It allows precise current regulation and maintains high LED current accuracy while consuming minimal power. With its comprehensive protection features and various voltage range options, the HV9985K6-G provides greater protection and system reliability for automotive and general lighting applications.
