PMIC - Power Management - Specialized

TDA3616T/N1,112 is a power management integrated circuit (PMIC) specialized in managing a wide range of voltage, current and temperature requirements. Specifically, it is capable of converting a single-phase AC supply into an isolated symmetrical three-phase DC bus, and then provides control and protection functions for the output three-phase voltage and current. The input single phase AC can range from 160 to 480VAC with a frequency range from 45 to 66Hz. The output voltage range is from 220 to 264VDC.

The heart of the TDA3616T/N1,112 is the NXP Nexperia TDA3616T integrated circuit (IC). This IC comprises of four main components; a power conversion block, a protection block, a three-phase PWM block and a multi-channel analog monitor block. The power conversion block is designed to convert a single-phase AC supply into an isolated three-phase bus, with adjustable output voltage and current. The protection block is a combination of a voltage monitor and a current monitor to provide both overload, short circuit and thermal protection. The three-phase PWM block is responsible for providing the output power switches, along with their current sensing and control. Finally, the multichannel analog block includes voltage, current and temperature monitoring and diagnostics. All components are interconnected by an internal bus and can be controlled by an external host microcontroller.

TDA3616T/N1,112 is mainly used in applications such as Uninterruptible Power Supplies (UPSs), Industrial Automation, Data Centers, and Electrical Appliances where a reliable and efficient power management system is required. It provides the necessary power conversion, current and voltage control and protection, as well as measurement and monitoring features for building a sophisticated and reliable power supply system.

When using the TDA3616T/N1,112, first the application is evaluated to determine the desired voltage and current requirements. Based on these requirements, the parameters of the power conversion block, the protection block and the three-phase PWM block should be adjusted. This is usually done by a microcontroller which is connected to the TDA3616T/N1,112 through an internal bus. Once all the parameters are adjusted and set, the power supply can be started and it will remain operational and reliable until the application requirements are changed.

In conclusion, the TDA3616T/N1,112 is a specialized PMIC that is suitable for applications requiring a reliable and efficient power management system. It can convert an AC supply into a three-phase DC bus, while providing protection and control functions. Combined with a suitable microcontroller, it can be used to build a sophisticated power supply system.
