The REFLVBMS001-EVK-001 facilitates the verification of the operation of ultra-efficient battery management solutions for the expanding IoT field. The REFLVBMS001-EVK-001 is equipped with a power supply IC (buck DC/DC converter IC) and reset IC (voltage detector IC) using the company’s original Nano Energy ultra-low current consumption technology.

In addition, it consists of a battery charger IC that supports low-voltage rechargeable batteries, along with the NGK INSULATORS’s thin, large capacity EnerCera li-ion rechargeable battery. The ultra-low current consumption of the power supply IC (quiescent current 180nA) minimizes loss.

The battery charger IC is suitable for a wide range of charge voltages; it is capable of charging, monitoring, and discharging batteries, making it ideally suited for compact IoT devices. The result is a low profile, ultra-efficient battery management solution that achieves a thickness of just 0.60mm for mounted components (including the thin rechargeable battery).

All mounted components are less than 0.60mm thick (1.60mm when including the board) – thus allowing use as a reference design for ultra-thin IoT applications such as smart cards.

Application examples include:

  • Wearables such as smart watches, keyless entry
  • Compact industrial IoT devices, including electronic shelf labels, smart cards, smart meters, and alarms
  • Other IoT equipment requiring smaller, thinner form factors and longer battery life

The board is available now.
