ROHM Group company LAPIS Technology developed a chipset capable of providing up to 1W of wireless power for compact and streamlined wearable devices, and for industrial smart, miniaturized and sealed solution. The ML7661 (transmitter) and ML7660 (receiver) eliminate the need for an external MCU by incorporating a control circuit required for transmission/reception, resulting in the industry’s smallest system size in the 1W class. This makes it ideal for wearables with a large battery capacity designed to be worn for long time frames. Typical products are wristband blood pressure monitors, fitness trackers, smart watches, and hearing aids, for example. Moreover, the adoption of the high 13.56MHz frequency band enables the support for Near Field Communication (NFC).

ROHM has recently added a new thermal analysis function to its ROHM Solution Simulator. The new feature allows designers of electronic circuits and systems in the automotive and industrial markets to collectively verify power devices and driver ICs thermal issues on different solution circuits.

ROHM has developed thick-film shunt resistors, LTR100L, optimized for industrial and consumer applications. Often used to detect current in battery protection and motor drive circuits, shunt resistors require higher accuracy to improve reliability and ensure high efficiency operation.

ROHM has recently been certified as a preferred supplier of SiC power solutions by United Automotive Electronic Systems Co., Ltd., (UAES), a Chinese Tier 1 comprehensive automotive manufacturer.

ROHM developed a battery charger IC – BD71631QWZ – designed to provide low-voltage charging of wearables like wireless ear buds and thin, compact IoT devices such as smart displays powered by rechargeable batteries.

The entire 178-product lineup contributes to lower power consumption, smaller size, and higher reliability in a wider range of applications.

ROHM’s new compact high accuracy barometric pressure sensor IC, BM1390GLV (-Z), featuring a waterproof rating of IPX8, is ideal for home appliances, industrial equipment, and compact IoT devices.

ROHM developed dual-MOSFET products (Nch+Pch) featuring ±40V/±60V withstand voltages, QH8Mx5/SH8Mx5 series. The devices are ideal for driving motors in base stations (cooling fans) and industrial applications such as factory automation equipment requiring 24V input.

High density emission along with the industry’s narrowest width supports longer distances and higher accuracy in LiDAR-equipped applications.
