PMICs, or Power Management ICs, are devices used widely in the electronics industry to manage, monitor, and optimize power consumption in a variety of electrical circuits. PMICs play an important role in electronics that require a moderate amount of power such as in embedded systems, consumer electronics, automotive, and other applications. One type of widely used PMIC is LED Drivers, which offer a cost-efficient and reliable solution to controlling LEDs.

The HV9801ANG-G application field and working principle LED Drivers are a popular choice used by circuit designers to drive LED light systems. This members of this device family are designed to provide a stable, current-controlled output for high-power LED lighting applications. The HV9801ANG-G is an N-channel MOSFET-based high-efficiency LED driver that supports a wide input voltage range from 3 V to 32 V, allowing it to work with most power sources available. It also features an adjustable output current up to 1.2 A and is capable of controlling up to 8 LEDs in parallel without requiring a boost converter.

The HV9801ANG-G LED driver employs a low-voltage off-time controller to effectively monitor the power consumption of each LED in the system. This is done by setting the peak current in the LED system, which is then continuously adjusted based on the LED’s on/off pattern and load. The HV9801ANG-G achieves high efficiency as it employs a switching MOSFET as the main power-switching element. It also features temperature protection, over-current protection, over-temperature protection, and over-voltage protection for reliable operational performance in a wide range of lighting applications.

The HV9801ANG-G LED driver consists of two inputs, one for the voltage filter, and the other for the current feedback signal. The voltage input passes through a filter circuit and then to the error amplifier. The error amplifier then compares the set current feedback signal to a reference signal generated by some fixed resistor which varies based on the current magnitude set on the device. Output voltage is then adjusted based on the difference between the feedback signal and the reference signal and is then prorated by the power MOSFET and given to the LEDs. The power MOSFET has its own adjustable temperature control element to ensure accurate control of the output.

HV9801ANG-G LED drivers offer a reliable and cost-efficient solution for designers who need to control LEDs in their applications. This device family features flexible current setting capability, temperature protection and over-current protection to ensure a safe, efficient, and reliable operation even when subject to demanding operations.

In short, the HV9801ANG-G LED driver provides a great solution that is both cost and energy-efficient. It is designed to efficiently monitor and control LED systems for applications with a moderate amount of power, making it great for embedded systems, consumer electronics, and other applications.
