R5432V SERIES
3 to 5 Cells Li-ion Battery Protector IC
NO.EA-263-1600711
OUTLINE
The R5432V is a high voltage CMOS-based protection IC for overcharge /discharge of rechargeable three-cell / four-cell / five-
cell Lithium-ion / Lithium- polymer battery, further include a short circuit and the protection circuits against the excess discharge
current and excess charge current.
Each of these ICs is composed of eighteen voltage detectors (fourteen for 3cell protection type, sixteen for 4cell protection
type), a reference circuit, a delay circuit, a short detector circuit, an oscillator, a counter and a logic circuit.
The output of COUT is P-channel open-drain type, and DOUT is CMOS type.
If the overcharge voltage or overcharge current is detected by the R5432V, after the preset output delay time, the output of
COUT becomes Hi-Z.
While the overdischarge voltage or current is detected, after the preset output delay time, the output of DOUT becomes ”L”.
After detecting overcharge voltage, when the cell voltage returns lower than the overcharge released voltage, then overcharge
is released and the output of COUT becomes “H”. After detecting overcharge current, by disconnecting a charger and
connecting a load, then overcharge current is released and the output of COUT becomes “H”.
After detecting overdischarge voltage, when the cell voltage becomes the released voltage from overdischarge or more,
then overdischarge is released and the output of DOUT becomes “H”. After detecting overdischarge current and short circuit,
by disconnecting the load, the function of the output of DRAIN pin, the external NMOSFET turns on, and VMP pin voltage is
pulled down by the resistance connected to GND and released overdischarge current or short and the output of DOUT becomes
“H”.
By forcing a certain voltage to SEL1 and SEL2 pins, the testing time of protection circuits can be short. Specifically,
overcharge, discharge, over current delay time can be shortening into approximately 1/80.
The R5432V can protect 6-cell or more by connecting 2 pieces of the R5432V in cascade. High side IC’s COUT and
DOUT must connect to CTLC and CTLD respectively of the low side IC. As a result, the signal of the high side of COUT and
DOUT is transmit to the lower side IC, and control FETs for charge and discharge.
The R5432V has cell-balance function to solve the unbalance condition of serially connected cells. If cell voltage is
beyond the cell balance detector threshold, by the output of the cell balance control pin, the external NMOSFET turns on, and
a current path is made, and during charge, charge current is bypassed, otherwise, cell is discharged until the cell voltage
becomes the released voltage from cell-balance operation.
If the connection between a cell and a protection board is broken, the open-wire condition is detected by the R5432V, and the
output of COUT becomes Hi-Z. After detecting the open-wire, when the cell and the protection board is connected again, the
open-wire detector is released and the output of COUT becomes “H”.
