ROHM developed a battery charger IC that supports low voltage charging of not only li-ion, but also new types of rechargeable batteries such as all-solid and semi-solid state. The BD71631QWZ achieves low voltage charging over a wide range from 2.0V to 4.7V by improving the stability of the internal circuit.

Unlike general battery charger ICs that provide a fixed voltage, ROHM’s new product allows the charge voltage to be easily set by simply changing the external resistor, reducing design load when changing batteries. Additionally, original package technology results in a compact package of just 0.4mm thickness, which is 60% lower than conventional products in the market. This is contributing to smaller, thinner devices. In addition, each charging characteristic like charge/termination current can be set for CCCV charging, providing an optimal charging environment for thin, compact IoT and wearable devices utilizing the latest rechargeable batteries.

Application Examples
  • Devices equipped with low voltage and single-cell li-ion rechargeable batteries
  • Wearables such as wireless earbuds, electronic pens, e-cigarettes, etc.
  • Smart displays/tags and other compact IoT devices

ROHM proposes laser diodes that support a wide range of needs in the consumer, industrial, and automotive markets, including high power metal CAN package types that provide high accuracy long range sensing with narrow emission width ideal for robot vacuums and AGVs (Automated Guided Vehicles). Also offered is a new surface mount VCSEL solution that allows for short distance wide range sensing and contributes to the miniaturization of LiDAR/ToF ranging modules by adopting a proprietary structure to achieve a single lobe narrow beam point, making it ideal for facial recognition, industrial robots and driver monitoring systems.


ROHM's optical sensors include high sensitivity, high-reliability phototransistors, infrared light-emitting diodes, transmission type photo interrupters, and reflective type photo interrupters.

In industrial and commercial applications, optical sensors are also being used for distance and temperature sensing and automation in Industry 4.0 applications. For example, optical sensors can detect liquid levels in process engineering facilities, such as petroleum levels in tank farms and hydrocarbon refineries, by integrating an infrared LED, light transistor, and a transparent prism tip.
