3-5 Cell Li-Ion/Li-Polymer Battery Protection Analog Front-End IC

Ricoh Europe (Netherlands) B.V. Semiconductor Support Centre has launched a Analog Front-End (AFE) Integrated Circuit (IC), the R5601. The new addition to Ricoh’s battery management ICs portfolio is designed for Lithium-ion or Lithium-polymer battery packs of three up to five cells in series. Applications include cordless power tools, robot vacuum cleaners, lawn mowers, and electrical bikes.

Traditional stand-alone protection ICs have internally fixed hardware settings for various monitoring thresholds that decide to interrupt the charge or discharge process and control the external dual MOSFET. The advantage of an AFE IC versus a stand-alone protection IC is the flexible concept enabling short time to the market. An AFE IC is a measurement device of which the results are forwarded to a MCU (microcontroller unit). The fact that all threshold settings are saved within the software of the MCU and software settings are easily adaptable means a significant advantage. Therefore, an AFE IC is more convenient to use as a standard measurement IC for various battery pack designs.
