ROHM Releases Evaluation Board for Ultra-Efficient Battery Management Solution for Small and Thin IoT Devices

     The world-renowned semiconductor manufacturer ROHM (headquartered in Kyoto, Japan) has developed an ultra-efficient battery management solution (suitable for various wearable devices, electronic shelf labels, smart cards, etc.) that can be easily evaluated for the growing IoT field. IoT device) evaluation board "REFLVBMS001-EVK-001"

     In recent years, battery-powered electronics have become ubiquitous, including mobile devices, wearables, and industrial IoT devices. For the components carried in these applications, in order to improve their design flexibility and performance, they are required to be smaller and thinner; in addition, in order to improve their convenience, the batteries are required to have larger capacity and reduce power consumption to a greater extent . ROHM has developed a variety of low-power analog ICs, including power supply ICs using ultra-low quiescent current technology "Nano Energy™" and charge control ICs supporting various secondary batteries. By providing targeted and excellent power solutions, it helps to achieve long-term operation of battery-operated applications. This time, combining these technical advantages, an evaluation board that can evaluate ultra-efficient battery management solutions for small and thin IoT devices has been developed and sold.

     The "REFLVBMS001-EVK-001" evaluation board is equipped with a power supply IC and reset IC using ROHM's ultra-low quiescent current technology "Nano Energy™", a charge control IC supporting new low-voltage secondary batteries, and a low-profile Capacity lithium-ion secondary battery "EnerCera®". The circuit is very suitable for small IoT devices. Among them, the 180nA ultra-low quiescent current power supply IC can reduce the power consumption of the power supply part in the application to a greater extent. At the same time, the charging control IC supporting a wider charging voltage range can be used for charging, monitoring and discharge control. Using this evaluation board, you can easily evaluate an ultra-thin and ultra-efficient battery management solution that achieves a thickness of only 0.60mm or less for all mounted components including thin secondary batteries.
