Integrated circuits for power management are known as power management integrated circuits (power management ICs, PMICs, or PMUs as a unit).
Although the term “PMIC” can apply to a wide variety of chips (or modules in system-on-a-chip devices), the majority of them contain several DC/DC converters or their control components.
In order to save space, PMICs are frequently used in battery-powered gadgets like mobile phones and portable media players.
To regulate power on electronic devices or in modules on devices that may have a range of voltages, a power management integrated circuit (PMIC) is employed.
The PMIC controls, among other things, scaling of voltages up or down, DC-to-DC conversion, and battery power charging and sleep modes.
The Global Programmable Power Management IC market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
ROHM Semiconductor BD71847AMWV Programmable Power Management IC. The programmable power management IC (PMIC) BD71847AMWV from ROHM Semiconductor is perfect for powering single-core, dual-core, and quad-core SoCs.
The BD71847AMWV integrates all of the power rails needed by the CPU and its system peripherals, making it specifically tailored for the NXP Semiconductors i.MX 8M Mini processors.
The development time can be cut down greatly due to this optimization, which also makes programme design simpler.
The BD71847AMWV’s power supply circuit combines six buck converters with six Low Dropout Regulators (LDOs) and control logic, enabling it to power both the processor and the necessary DDR memory.
Along with a 32.768kHz crystal oscillator driver, an output short-circuit protection circuit, an output over-voltage/current protection circuit, and a thermal shutdown circuit, the device also includes a 1.8V/3.3V power switch for SDXC cards.
For 0.7V to 3.3V output, buck conversion efficiency of 83% to 95% is obtained, and the large input voltage range of 2.7V to 5.5V accommodates a variety of power sources, including batteries and USB.
The NXP i.MX 8M Mini processor and DDR memory are easily connected to the BD71847AMWV PMIC thanks to its small 7mm x 7mm 56-pin QFN (Quad Flat No-lead) packaging, which significantly reduces design work and PCB space.
