ROHM offers PMICs aimed at Intel Bay Trail I platform

ROHM Co. Ltd has announced a line of power management ICs (PMICs) based on the Intel Atom processor E3800 family. The Intel Atom processor E3800 product family is a SoC designed for intelligent systems, delivering outstanding compute, ECC, HD graphics processing, and media performance while operating in an extended range of thermal conditions, noted the company.

Based on the Silvermont microarchitecture, the devices are fabricated on Intel's 22nm process with 3D Tri-Gate transistors, which deliver significant improvements in performance and energy efficiency. The firm added that the family members offer low power consumption levels that range from 6-10W.

Intel's latest product family is geared for a range of applications such as in-vehicle infotainment systems, interactive kiosks, intelligent vending, ATMs, point-of-sale terminals as well as portable medical devices.

ROHM PMICs claim to use superior analog technology, ensuring outstanding performance in the most demanding applications.

The BD9596MWV, integrates an intelligent power supply core with transient load response, along with a 16-channel system power supply consisting of a 2-channel DC/DC controller, 3channel DC/DC regulator, 2-channel IMVP7 Lite controller, 8-channel LDO and 1-channel load switch, all in a single 10mm² package. This eliminates the need for users to develop and verify their own complex power solution that requires complicated sequences and associated circuit design, with multiple analog components, in a larger PCB area.

In addition, the startup sequence and clock function is built in, compatible with the Intel Atom processor E3800 product family, (which is typically controlled by a MCU), reducing customer design effort significantly. ROHM PMICs also reduce mounting area by 50 percent and requires 40 percent fewer parts than comparable discrete configurations, contributing to end-product miniaturization and improved reliability, stated the firm. Additional features include multiple protection circuits (i.e. UVLO, TSD, SCP, OVP), a wide operating temperature range (-40掳C to 95掳C), and a built-in power supply that operates from 3.5V and maintains stable operation even during supply voltage drops, ensuring support even for automotive applications.

Besides the BD9596MWV, designed for industrial applications, ROHM offers the automotive-grade BD9596MWV-M.
