R5432V Series
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. Disconnection detection and cell-balance function, which can reduce cell-unbalance, are available. Package is SSOP-24.
