LC05511XA, LC05512XA www.onsemi.com DESCRIPTION OF OPERATION The battery voltage is detected between VCC pin and VSS pin and the battery current is detected between VSS pin and CS pin. (1) Normal State

• “VCC voltage” is between “over-discharge detection voltage (Vuv)”, “over-charge detection voltage (V ov)”, and “CS voltage” is between “charge over-current detection voltage (Vcoc)”, “discharge over-current detection voltage (Vdoc)”, and “VM voltage” is lower than “dicharge over-current (short) release voltage (Vdocr)”. This is the normal state. Both CO and DO are high level output. Charge and discharge is allowed. (2) Over-charging State
• “VCC voltage” is higher than or equal to “over-charge detection voltage (V ov)” for longer than “over-charge detection delay time (Tov)”. This is the over-charging state, CO is low level output. Charge is prohibited.
• Release from Over-charging State 1 “VM voltage” is lower than “charge over-current (short) release voltage (Vcocr)”. Then “VCC voltage” is lower than “over-charge release voltage1 (V ovr1)” for longer than “over-charging release delay time (Tovr)”.
• Release from Over-charging State 2 “VM voltage” is higher than “charge over-current (short) release voltage (Vcocr)”. Then “VCC voltage” is lower than “over-charge release voltage2 (V ovr2) for longer than “over-charge release delay time (Tovr)”. (3) Over-discharging State
• “VCC voltage” is lower than “over-discharge detection voltage (Vuv)” for longer than “over-discharge delay time (Tuv)”. This is the over-discharging state, DO is low level output. Discharge is prohibited. During over-discharging state, VM pin is pulled up to Vcc by internal resistor (Rvmu) and circuits are shut down. The low power consumption is kept.
• Release from Over-discharging State 1 Charger is connected, then “VCC voltage” goes higher than “over-discharge release voltage1 (Vuvr1)” for longer than “over-discharge release delay time (Tuvr)”.
• Release from Over-discharging State (with Auto Wake-up Feature) 2 (LC05511XA) “VCC voltage” is higher than “over-discharge release voltage2 (Vuvr1)” without charger for longer than “over-discharge release delay time (Tuvr)”. (4) Discharging Over-current State
• Discharge Over-current Detection 1 CS terminal is higher than or equal to “discharge over-current detection voltage (Vdoc1)” for longer than “discharge over-current detection delay time (Tdoc1)”. DO is low level output. Discharge is prohibited.
• Discharge Over-current Detection 2 CS terminal is higher than or equal to “discharge over-current detection voltage2 (Vdoc2)” for longer than “discharge over-current detection delay time 2 (Tdoc2)”. DO is low level output. Discharge is prohibited.
• Discharge Over-current Detection (Short Circuit) CS terminal is higher than or equal to “discharge over-current detection voltage (Short circuit) (Vshrt)” for longer than “short-current detection delay time (Tshrt)”. DO is low level output. Dischaege is prohibited. During discharging over-current state, VM pin is pulled down to Vss by internal resistor (Rvmd).
• Release from Discharging Over-current State “CS voltage” goes lower than “discharge over-current detection voltage (Vdoc1)” and VM voltage goes lower than “discharge over-current (short) release voltage (Vdocr)” for longer than “discharge over-current release delay time (Tdocr)”. (5) Charging Over-current State
• “CS voltage” goes lower than or equal to “charge over-current detection voltage (Vcoc) for longer than “charge over-current detection delay time (Tcoc)”. This is the charging over-current state, CO is low level output. Charge is prohibited.
• Release from charging over-current state “CS voltage” goes lower than “charge over−current detection voltage (Vcoc)” and “VM voltage” goes lower than “charge over-current release voltage (Vcocr)” for longer than “charge over-current release delay time (Tcocr)”. (6) 0 V Battery Charging (LC05511XA)
• When the Battery voltage is lower than or equal to “0 V battery charge permission voltage (Vchg)”, charge is allowed if charger voltage is higher than or equal “0 V battery charge permission voltage (Vchg)”. CO is fixed by the “VCC voltage”. (7) 0 V Battery Protection Function (LC05512XA)
• This function protects the battery when a short circuit in the battery (0 V battery) is detected, at which point charging will be prohibited. When the voltage of a battery is below “0 V battery charging inhibition battery voltage (Vinh)”, CO is low level output. Charge is prohibited.
