BATTERY PROTECTION 3-SERIAL-CELL PACK S-8233C Series Description
Remark Refer Normal condition Battery Protection Connection Example".
This monitors voltages three serially-connected batteries discharge current control charging discharging. voltages three batteries range from over discharge detection voltage (VDD) over charge detection voltage (VCU), current flowing through batteries becomes equal lower than specified value (the terminal voltage equal lower than over current detection voltage charging discharging FETs turn this condition, charging discharging carried freely. This condition called normal condition. this condition, output voltage CSO,ISO `low'. terminals shorted RVCM resistor. Over current condition This provided with three over current detection levels (VIOV1,VIOV2 VIOV3) three over current detection delay time (tIOV1,tIOV2 tIOV3) corresponding each over current detection level. discharging current becomes equal higher than specified value (the terminal voltage equal higher than over current detection voltage) during discharging under normal condition continues over current detection delay time (tIOV) longer, discharging turns stop discharging. This condition called over current condition. terminals shorted RVCM resistor this time. charging turns off. When discharging load connected, terminal voltage equals potential. this condition, output voltage goes `High'. over current condition returns normal condition when load released impedance between terminals (see Figure connection example) higher. When load released, terminal, which terminal shorted with RVCM resistor, goes back potential. detects that terminal potential returns over current detection voltage (VIOV1) lower over current detection voltage (VIOV2) lower COVT terminal fixed level over current detection inhibited) returns normal condition. that time, output voltage goes `Low'. Over charge condition battery voltages becomes higher than over charge detection voltage (VCU) during charging under normal condition continues over charge detection delay time (tCU) longer, charging turns stop charging. This condition called over charge condition. level signal output conditioning terminal corresponding battery which exceeds over charge detection voltage until battery becomes equal lower than over charge release voltage (VCD). this condition, output voltage `High'. terminals shorted RVCM resistor under over charge condition. over charge condition released cases. output voltage terminal changes when over charge condition released. battery voltage which exceeded over charge detection voltage (VCU) falls below over charge release voltage (VCD), charging turns normal condition returns. battery voltage which exceeded over charge detection voltage (VCU) equal higher than over charge release voltage (VCD), charger removed, load placed, discharging starts, charging turns normal condition returns. release mechanism follows: discharge current flows through internal parasitic diode charging immediately after load installed discharging starts, terminal voltage decreases about from terminal voltage momentarily. detects this voltage (over current detection voltage higher), releases over charge condition returns normal condition.

Over discharge condition battery voltages falls below over discharge detection voltage (VDD) during discharging under normal condition continues over discharge detection delay time (tDD) longer, discharging turns discharging stops. This condition called over discharge condition. this condition, output voltage goes `High'. When discharging turns off, terminal voltage becomes equal voltage IC's current consumption falls below power-down current consumption (IPDN). This condition called power-down condition. terminals shorted RVSM resistor under over discharge power-down conditions. power-down condition canceled when charger connected voltage between higher (over current detection voltage When battery voltages becomes equal higher than over discharge release voltage (VDU) this condition, over discharge condition changes normal condition. this condition, output voltage goes `Low'. Delay circuits over charge detection delay time (tCU1 tCU3), over discharge detection delay time (tDD1 tDD3), over current detection delay time (tIOV1) changed with external capacitors C6). delay times calculated following equations: Min. Typ. Max. tCU[s] =Delay factor 1.07, 2.13, [uF] tDD[s] =Delay factor 0.20, 0.40, [uF] tIOV1[s]=Delay factor 0.10, 0.20, [uF] Caution delay time over current detection fixed internal circuit. delay time cannot changed external capacitor. terminal terminal floated under normal condition, pulled potential both charging discharging FETs turn inhibit charging discharging. Both charging discharging also inhibited applying terminal terminal externally. this time, terminals shorted RVCM resistor. When terminal becomes equal potential, charging discharging enabled back their appropriate conditions battery voltages.
Caution Please note unexpected behavior might occur when electrical potential difference between ('L' level) generated through external filter (RVSS CVSS) result input voltage fluctuations.
battery charging function This function used recharge three serially-connected batteries after they self-discharge When charging start voltage (V0CHAR) higher applied between connecting charger, charging gate fixed potential. When voltage between gate sources charging becomes equal higher than turn-on voltage charger voltage, charging turns start charging. this time, discharging turns charging current flows through internal parasitic diode discharging FET. battery voltages become equal higher than over discharge release voltage (VDU), normal condition returns. CAUTION products without battery charging function, resistance between between lower than products with battery charging function. causes that over charge detection voltage increases drop voltage (see Figure connection example) with sink current VMP. output undefined below VCC-VSS voltage products without battery charging function.
