RICOH R5403x, R5405x Technical data
R5403x/R5405x Series
Li-ion/polymer 1Cell Protector
R5403x/R5405x Series are high input voltage CMOS-based protection ICs for over-charge/discharge of rechargeable one-cell
Lithium-ion (Li-ion) / Lithium polymer excess load current, further include a short circuit protector for preventing large external short
circuit current and excess charge/discharge-current. Each of these ICs is composed of four voltage detectors, a reference unit, a
delay circuit, a short circuit protector, an oscillator, a counter, and a logic circuit.
In addition to SOT-23-5 and SOT-23-6 packages, DFN(PLP)1616-6, DFN(PLP)1820-6 are also available.
