Power Management Integrated Circuits (PMICs) are dedicated integrated circuits that are designed to provide an easy-to-use solution for managing power in electronic systems. PMICs have been around since the early days of digital technology and have become increasingly popular in recent years. This is largely due to the increasing availability of programmable devices, the ever-growing complexity of embedded designs, and the greater need for higher performance levels. While PMICs cover a broad range of functions, there are certain specialized products which are aimed at specific applications or markets. HMC981LP3ETR is one such specialized device.

The HMC981LP3ETR is a single-chip 3-phase inverter controller, designed to provide efficient and cost-effective PFC (power factor correction) and active harmonic generator control. It is optimally suited for the growing demand of energy-efficient industrial motor drives and advanced control requirements. This device operates from a supply voltage range from 8 V to 38 V, and can provide up to 12 A of continuous output current.

The primary purpose of this device is to provide a solution for controlling the power factor of industrial motor drives. By actively correcting the power factor of the grid, the HMC981LP3ETR can ensure that the motor drives are operating with maximum efficiency and minimum power loss. The device also supports active power factor correction with digital control, enabling the user to tailor the control algorithm to the specific application. Additionally, the HMC981LP3ETR can be used to control the harmonic contents of the motor drive, helping to reduce harmonics in the grid and improve the overall power quality.

The HMC981LP3ETR is based on advanced mixed-signal technology and utilizes a multi-channel Pulse Width Modulation (PWM) scheme to achieve high efficiency. The device includes built-in control circuitry, and uses a highly efficient cycle-by-cycle current control loop to provide fast response. Additionally, it features built-in Fault and Overload management, so that the motor drives are automatically shut off in case of a fault or overload situation.

The HMC981LP3ETR is designed for use in systems with a wide range of needs, including industrial motor drives, home appliance and lighting applications, solar inverters, and general purpose three-phase inverters. Additionally, it can be used to control the output power of LED lighting systems, enabling precise control of the light intensity and flicker. This device is also fully compatible with any modulating input, such as 1-10V, DALI, or RGB, so that it can easily be integrated into existing systems.

To use the HMC981LP3ETR in an application, it needs to be connected to a suitable power supply and programmed with the required configuration and control parameters. The power supply must be able to support the current and voltage requirements of the device, and the control software must be programmed to match the requirements of the application. For example, if the application requires a maximum output of 12 A, then the software must be configured to limit the maximum output to 12 A. Additionally, since the device uses PWM for control, the frequency of the PWM signal must be configured to match the needs of the application.

In summary, the HMC981LP3ETR is a specialized power management device that can be used to provide efficient and cost-effective control of industrial motor drives. It is based on advanced mixed-signal technology and provides active harmonic generator control and active power factor correction with digital control. Additionally, it is fully compatible with any modulating input, such as 1-10V, DALI or RGB, allowing it to be easily integrated into existing systems. With its wide range of features and versatile programming, the HMC981LP3ETR is an invaluable tool for application designers and power management engineers.
