Power management integrated circuit (PMIC), is a microchip package with multiple voltage regulators, clock and power control components, which is located in a smartphone or other embedded system. PMIC supervisors, is the subcategory of PMIC which mainly deals with the power-on resetting, voltage monitoring, temperature control, and others to ensure a steady power supply. TPS3306-33DG4 is a member of PMIC supervisors and has a wide range of application fields. This paper will mainly focus on TPS3306-33DG4 application field and working principle.

Application Field

TPS3306-33DG4 is applied in a wide range of devices and applications. It contributes in motherboard and notebook powered by Intel, AMD and VIA to provide over- and under-voltage protection and in-rush current protection for core voltage, remote voltage monitoring and shut down platform boards. It is also used in game consoles, CD-ROM, fixed-line hard drives, set-top boxes, CD drivers and other electronic products, which helps to supply more stable and secure power. In wireless device, TPS3306-33DG4 can be used to provide power supply for circuit boards, charging products and other intelligent control. To simplify their circuit design, many manufacturers also choose to use TPS3306-33DG4 in their linear charger, power management modules, smart coat, and other portable devices.

Working Principle

TPS3306-33DG4 uses a new generation of hybrid main technical scheme to replace traditional discrete components configuration scheme. In order to increase output voltage protection, TPS3306-33DG4 is manufactured based on charge performance of VClamp technology (Voltage Clamp at Die Level Technology) combined with the traditional technology to construct an effective bridge between the die and pin level, with on-chip MOSFET integrated in it. This means hybrid components mainly consists of two-stage active clamp settings, with the control of the MOSFET, to ensures high power and improved voltage overshoot protection.

Besides, TPS3306-33DG4 also uses a specially designed power-on reset IC (power on reset) tool, to ensure high precision detect line voltage, to ensure that the load auto start-up once the power line return to its normal voltage, and also reset itself when too much power is used. During applying process, TPS3306-33DG4 extends its operating temperature range further and make a good performance even in the higher end, to ensure the quality of output voltage.

Conclusion

Various kinds of PMIC supervisors have integral functions to steady the power supply in different devices. TPS3306-33DG4, as a part of PMIC supervisors, has a wide range of application fields and tech-driven working principles to help supply more secure power. It is mainly used to provide voltage protection, temperature control, remote voltage monitoring and shut down platform boards, which plays a vital role in electronic device and portable device.
