ROHM now offers the availability of the BD71847AMWV, a highly integrated and efficient PMIC optimised for NXP Semiconductors’ i.MX 8M Mini family of application processors, which provides exceptional computing, video, audio, and graphics performance. The device is the newest addition to the company's expanding portfolio of PMICs created for NXP’s i.MX application processors. With the new device, the company has power solutions for all members of the i.MX 8M family.


“ROHM is a valued i.MX ecosystem partner. The BD71847AMWV is a good choice for our i.MX 8M Mini applications processors customers looking to maximize performance. It is also available mounted on a reference board, providing a single-chip power solution optimized for processors,” said Leonardo Azevedo, i.MX senior director of marketing at NXP Semiconductors.


i.MX 8M Mini applications processors enable customers to include voice interface to audio/video streaming devices at a minimal cost. They integrate up to four ARM Cortex-A53 cores operating up to 1.8GHz along with an ARM Cortex-M4 that operates at up to 400MHz for low standby power consumption. Also, support for 1080p video processing, 2D/3D graphics, advanced audio functions, and numerous high-speed interfaces makes the i.MX 8M Mini perfect for a broad variety of consumer and industrial applications.


Leveraging the company's expertise in analog power and advanced BCD process, the device combines all power rails needed by the processor as well as power supplies for DDR and common system IO. As well as to DC-DC converters with industry-leading efficiency of 95%, the PMIC features programmable power sequencer for flexible power control and management, buffered sleep clock, seamless hardware control interface to i.MX 8M Mini, protection functions, etc.. The high level of integration, customisations for i.MX 8M Mini applications processors and programmability assist in shortening development time, lower system BOM cost, and minimise solution footprint.
