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 voltage (V ovr)” 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 detection voltage (V ov) 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−charge release delay time (Tuvr)”.
- Release from Over −discharging State (with Auto Wake−up Feature) 2 “VCC voltage” is higher than “over −discharge release voltage2 (Vuvr1)” without charger for longer than “over−charge release delay time (Tovr)”. 4. Discharging Over−current State
- Discharge Over−current Detection CS terminal is higher than or equal to “discharge over−current detection voltage (Vdoc)” for longer than “discharge over−current detection delay time (Tdoc1)”. 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 (Vdoc)” 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 higher than “charge over −current detection voltage (Vcoc)” and “VM voltage” goes higher than “charge over−current release voltage (Vcocr)” for longer than “charge over −current release delay time (Tcocr)”. 6. 0 V Battery Charging
- 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”.
