The R5433V Series are high voltage CMOS-based protection ICs for over-charge/discharge of rechargeable 3/4/5cell Li-ion/Lithium polymer battery. Each of these ICs is composed of ten voltage detectors, reference units, a delay circuit, an oscillator, a counter, and logic circuits. Disconnection between the battery and the protection board can be detected. SSOP-16 package is available.
The Ricoh R5433V Series consists of high voltage CMOS-based protection ICs designed for over-charge and over-discharge protection of rechargeable 3, 4, or 5-cell Li-ion and Lithium polymer battery packs. Each IC integrates ten voltage detectors, reference units, a delay circuit, an oscillator, a counter, and logic circuits to manage battery safety.
