Ricoh Electronic Devices Company R5617 Series Battery Protection ICs provide overcharge, over-discharge, and charge/discharge overcurrent protection for one-cell Li-ion and polymer batteries. The R5617 Battery Protection ICs feature an ultra-high overcharge detection of ±10mV, enabling the R5617 Series to ensure safety against overcharge and fully use the battery capacity. Also, the low 2µA power consumption of the R5617 ICs minimizes their own battery drain. The Ricoh Electronic Devices Company R5617 Series Battery Protection ICs are offered in a compact DFN1814-6B package and an ultra-small WLCSP-6-P13 package ideal for space-constrained applications.
