HPA01055DRBR Application Field and Working Principle

PMIC (Power Management Integrated Circuit) is a type of integrated circuits used to properly manage power systems in electronic devices. It is designed to supply, switch and regulate/monitor power in an efficient manner. Among other applications, PMIC can be used in power supply controllers, monitors and system on chip (SoC). HPA01055DRBR is one such family of PMICs.

HPA01055DRBR is a specialized PMIC that integrates a high power density isolated DC/DC converter with a buck and flex-configurable (boost + buck-boost) charger and the monitoring of several indirect power rails. This power supply management integration includes both a controller/monitor and an isolated DC/DC converter. It consists of an integrated step-down controller, a buck charger controller, a buck-boost charger controller and voltage monitors for overvoltage, undervoltage and over-temperature detection.

HPA01055DRBR is designed to be used in automotive applications and targeted applications include, but are not limited to, portable audio and video equipment, portable medical devices and electric vehicles. Once the target application is determined, designers can adjust the current limit, voltage and other parameters with the help of the related design tools of HPA01055DRBR. With its high integration level and low external parts count, it can reduce board size and cost.

Working Principle

HPA01055DRBR is designed with a dual-stage architecture which is comprised of a controller/monitor (for high-frequency operation) and an isolated DC/DC converter (for low-frequency operation). This dual-stage architecture helps to efficiently provide power to any system with a maximum output power of up to 25W and an operating temperature from -40°C to 150°C.

At the controller/monitor level, HPA01055DRBR is designed with Buck, Buck-Boost, and Boost power supply controllers. The buck controller features several characteristics like dynamic voltage scaling and programmable overvoltage protection. It also features an adjustable current limit and voltage. The buck-boost controller supports up to 2.5A and provides programmable output overvoltage protection as well as an adjustable current limit and voltage. The Boost supply provides an adjustable current limit and voltage.

At the isolated DC/DC converter level, HPA01055DRBR is comprised of an external transformer and an integrated high-voltage DC/DC converter (HVCDC) with the primary and the secondary windings connected in parallel. The HVCDC is designed to support a nominal operating frequency of 40kHz and its output voltage is adjustable in a range from 0.6V to 24V. The main features of the converter include surge protection, voltage monitoring, overload protection, and short-circuit protection.

HPA01055DRBR also provides several monitoring features such as programmable overvoltage protection, undervoltage protection, and over-temperature protection. The overvoltage and undervoltage thresholds are adjustable and these features help to ensure that the outputs remain safe and within the correct ranges.

Additionally, the HPA01055DRBR supports a wide range of digital communication interfaces, including I2C and CAN, which allow the monitoring of the status of each stage and the programming of certain parameters.

Conclusion

HPA01055DRBR is a specialized family of PMICs designed for automotive applications. It provides all the necessary functionalities for effective and efficient power management and monitoring. The integrated step-down controller, buck charger controller, buck-boost charger controller and voltage monitors help to ensure that the outputs remain safe and within the correct voltage range. Additionally, the support for I2C and CAN communication interfaces allows for the monitoring and programming of certain parameters. With its high integration level and low external parts count, it can reduce board size and cost, making it an ideal solution for any power supply management application.
