ROHM introduces a complete system PMIC for Intel Bay Trail I platforms




ROHM Semiconductor announced the general availability of Power Management ICs (PMICs) based on the Intel® AtomTM processor E3800 family. The Intel® AtomTM processor E3800 product family is a system-on-chip designed for intelligent systems, delivering outstanding compute, ECC, HD graphics processing, and media performance while operating in an extended range of thermal conditions. Based on the Silvermont microarchitecture, these devices are fabricated on Intel’s industry-leading 22nm process with 3-D Tri-Gate transistors, which deliver significant improvements in performance and energy efficiency. The family members offer low power consumption levels that range from 6 to 10 Watts.

Used in combination with ROHM’s optimized power management solutions, which feature industry-leading power conversion efficiency, results in systems that also deliver very low power consumption, with a minimal PCB footprint, and few external parts. Intel’s newest product family is ideally suited for a broad range of applications such as in-vehicle infotainment systems, interactive kiosks, intelligent vending, ATMs, point-of-sale terminals as well as portable medical devices.

“With the low power features of the new Intel® AtomTM processor E3800 product family, solutions like ROHM’s new PMICs provide better energy conversion efficiency that provide a number of performance benefits for a variety of markets,” said Sam Cravatta, product line manager, Intel Intelligent Systems Group.

“Our latest product, a PMIC designed for the next-generation Intel® AtomTM processor E3800 product family, has its roots in a chipset launchedin September 2010 for the Intel® AtomTM processor E6xx series. This PMIC also enables tablet designs, and was introduced in March 2013. In the future, in addition to our lineup of power management ICs for Intel® AtomTM processor families, we are committed to strengthening our support for a wide range of markets, from consumer devices such as digital AV equipment to industrial applications,” said Takahiro Ota, Director, ROHM LSI Corporate Strategy Headquarters.

The BD9596MWV integrates an intelligent power supply core with transient load response, along with a 16channel system power supply consisting of a 2channel DC/DC controller, 3channel DC/DC regulator, 2channel IMVP7 Lite controller, 8channel LDO, and 1channel 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® AtomTM processor E3800 product family,(which is typically controlled by a microcontroller), reducing customer design effort significantly. ROHM PMICs also reduce mounting area by 50% and requires 40% fewer parts than comparable discrete configurations, contributing to end-product miniaturization and improved reliability. Additional features include multiple protection circuits (i.e. UVLO, TSD, SCP, OVP), a wide operating temperature range (-40°C to 95°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.
