Integrated power management integrated circuits (PMICs) are semiconductor components specially designed to monitor and control the supply of power to the electronic circuitry of a system. These components provide multitasking functions, such as power conversion, linear regulation, monitoring, cyclic control, and low-power sleep modes. Many PMICs are packetized, meaning they contain multiple integrated components, such as buck and boost regulators, linear regulators, and current limiters. These provide power conversion, motor control, and battery management in a single compact unit. The BD8162AEKV is an advanced integrated PMIC manufactured by ROHM Semiconductor. It is a 4-channel power management integrated circuit that provides high-performance voltage regulation and power conversion for multiple low-power systems on a single die. It is designed for flexibility, scalability, and ease of integration, making it ideal for use in a wide range of applications.The BD8162AEKV has a wide range of application fields. It is ideal for a variety of low-power applications, such as LED lighting, wearables and IoT, audio products, and portable medical devices. The device also provides high efficiency, high-density, and low-heat operation, which makes it suitable for high-reliability and high-density power management applications.The BD8162AEKV can operate in two different modes: fixed frequency mode and pulse frequency modulation (PFM) mode. In fixed frequency mode, the output voltage is regulated by controlling the switching frequency. In PFM mode, the device operates at a constant frequency, but the duty cycle of the switching signal is modulated to control the output voltage. This provides better efficiency and lower output dynamic losses at light load conditions.The BD8162AEKV also includes a wide range of protection functions to guard against various external conditions. To ensure safe operation, the device is equipped with an internal over-voltage protector (OVP), under-voltage protection (UVP), short-circuit protection (SCP), and an over-temperature protector (OTP). It also includes an external error amplifier that can detect irregular output voltage conditions and inform the system of any failure.Additionally, the BD8162AEKV also employs ED2 process technology to reduce thermal resistance while providing higher efficiency and better thermal performance. This allows the device to withstand higher power densities, making it suitable for a variety of applications.In summary, the BD8162AEKV is a powerful, highly efficient PMIC designed for power conversion, motor control, and battery management in low-power applications. It provides high-performance voltage regulation and power conversion, while also offering a wide range of protection mechanisms. It is ideal for use in LED lighting, wearables and IoT, audio products, and portable medical devices. Thanks to its ED2 process technology, the device offers better thermal performance and higher power density.
