R5403x/R5405x Series is a high input voltage CMOS-based protection IC 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.
The Ricoh R5403x/R5405x Series are high input voltage CMOS-based protection ICs designed for over-charge and over-discharge protection of rechargeable one-cell Lithium-ion and Lithium polymer batteries. These devices also include short circuit protection to prevent large external short circuit currents and excess charge/discharge currents.
The ICs are composed of four voltage detectors, a reference unit, a delay circuit, a short circuit protector, an oscillator, a counter, and a logic circuit. They are available in SOT-23-5, SOT-23-6, DFN(PLP)1616-6, and DFN(PLP)1820-6 packages.
