The HV9963NG-G-M934 is a popular monolithic high voltage integrated circuit (IC) used as a PMIC (Power Management Integrated Circuit) and an LED driver. This device is capable of driving multiple strings of LEDs up to 200mA. It is commonly used in automotive lighting applications, as well as for home and commercial lighting systems.

The HV9963NG-G-M934 is designed to provide constant current drive in order to maintain consistent lighting performance across multiple LED strings. This is achieved by regulating the internal output current, regardless of variations in the input voltage or LED string characteristics. The device also offers flexible input voltage options, allowing it to be used with a wide range of power supply sources.

In addition to its constant current drive capabilities, the HV9963NG-G-M934 also offers several other features that make it an attractive choice for LED drivers. It has a wide range of dimming functions, including pulse width modulation (PWM) dimming, digital serial control (DSC) dimming, or a combination of both. It also has built-in thermal protection and an over-temperature shutdown feature, which helps to protect the device from being damaged by excessive heat. This device is also RoHS compliant, making it suitable for use in many different applications.

The working principle of the HV9963NG-G-M934 is quite simple. It contains an internal linear current regulator that maintains a constant output current despite variations in the input voltage or LED string characteristics. The regulator is triggered when a digital signal is received from the control circuit. This signal is used to adjust the device\'s internal reference voltage and thus regulate the output current.

The HV9963NG-G-M934 is a versatile, low-cost solution for automotive, home, and commercial lighting application needs. It offers great flexibility in terms of input voltage range, current regulation capabilities, and temperature protection. It is also RoHS compliant and can be used in a wide range of applications. With its combination of features, the HV9963NG-G-M934 is an ideal choice for any project requiring a reliable and high-quality LED driver.
