Power management integrated circuit (PMIC) is an important enabling technology for modern integrated circuit design. The P9023BR-4AHGI is a versatile, four-phase PMIC specifically tailored for embedded designs that require a high level of efficiency and power management performance. Its advanced design integrates power conversion, energy management, protection, and analog voltage regulation in one package, providing an all-in-one power solution for applications from embedded computing to mobile devices.

The P9023BR-4AHGI is a Four-Phase PMIC capable of delivering 4 x 100 A peak phase currents on any one channel and utilizes field-effect transistors (FETs) and control logic to facilitate phase control and current sharing between multiple phases. It offers four phase-controlled outputs which are independent from one another and have a fixed switching frequency. This four-phase controller provides several power management functions, including a wide operating temperature range, integrated start-up, overcurrent protection and thermal protection.

The power control logic in the P9023BR-4AHGI is designed to accurately control phase current levels, while providing a wide range of output voltage regulation. The voltage regulation feature has a fine trim and offset capability, allowing the user to tune the output voltage as needed. In addition, advanced features such as adaptive current sharing, over-current protection, thermal protection and external remote sensing are all integrated into the device.

The P9023BR-4AHGI is designed with robust power control circuitry that can operate over a wide voltage range, making it suitable for use in embedded and automotive applications. This power management device offers comprehensive input and output overvoltage protection and flexible current share settings to meet the needs of most embedded applications. It can be used to power high-current applications such as memory, DSPs, digital signal processors, or video processors.

The operation of the P9023BR-4AHGI is based on a constant frequency current mode control. It uses inputs from feedback control circuits, which measure the output voltage and current, to adjust the inductor current and output voltage. The pulse-width modulation (PWM) gate drive signals are generated by a PLL that is supplied by the internal clock source. The clock frequency is selected in order to ensure optimal efficiency and to obey safety regulations.

The P9023BR-4AHGI offers an integrated package with sophisticated features that allow it to support multiple system-level power management functions. It is designed to deliver efficient and power management performance in a wide variety of embedded and automotive applications. Its flexible power control architecture and input/output protection make it an ideal choice for designers looking for a high-performance PMIC solution.
