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 (Vov)" for longer than "over-charge detection delay time (Tov)".

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)". 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)". 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".
