RICOH R5463K Technical data
R5463K Series
High Accuracy Li-ion/polymer 2Cell protector
The R5463x Series are high voltage CMOS-based protection ICs for over-charge/discharge of rechargeable two-cell Li-ion/Lithium
polymer, further include a short circuit protection circuit for preventing large external short circuit current and the protection circuits
against the excess discharge-current and excess charge current.
Each of these ICs is composed of six voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a
counter, and logic circuits.
