The R5432V 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 voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a counter, and logic circuits. A more than 6 Cells battery is available by Cascade connection.
The Ricoh R5432V Series consists of high-voltage CMOS-based protection integrated circuits designed for over-charge and over-discharge protection of rechargeable 3, 4, or 5-cell Li-ion and Lithium polymer battery packs. These ICs integrate voltage detectors, reference units, delay circuits, short circuit protectors, oscillators, counters, and logic circuits. A cascade connection allows for the creation of protection circuits for batteries with more than 6 cells. The series also features disconnection detection and a cell-balance function to reduce cell unbalance, available in an SSOP-24 package.
