Lithium-ion batteries has high energy density and low memory effect and will be used in storage likes battery-powered equipment and solar power as well as automotive .
To safely and efficiently use a battery , the management of the series connected cells is important. This IC(*) has high precision AD converter for 16-series cells
to measure battery voltage and charge/discharge current and equalizes the cell voltage. It has the protection function for battery voltage and over- current detection for safety.
The micro computer with communication function for battery management , analog IC and power devices are prepared.
* Under development.
