Ricoh's 2 Lithium Ion

Ricoh's 2-cell Li-Ion/Polymer protection IC is a high-precision protection IC. In particular, the R54612 series has an overcharge detection accuracy of +10mV (ultra-high accuracy) in the temperature range of 0°C to 50°C. This series of Hongkang HY2120 will have some pressure to replace, because the accuracy of HY2120 is ± 25mV, but the replacement of R5460 is not a problem. The following is the parameters of R5460. Like HY2120-OB can replace the following many protection ICs, such as R5460N202AA, the specifications are almost the same. R5460N206AA,R5460K214AC
High-precision detector threshold .......................................... Overcharge detection (Topt = 25°C) ±25mV
