LC05551XA
Battery Protection IC,
OTP Function,
1‐Cell Lithium‐Ion Battery
Overview
LC05551XA is a protection IC for 1 cell lithium-ion or
lithium-polymer battery with built-in OTP. It provides highly accurate
adjustable over-charge, over-discharge, over-current protection with
adjustable detection delay by OTP. Current is detected by high
precision external chip resistor. Which realizes accurate current
detection over temperature. LC05551XA can control external FETs.

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.
“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.
(1) Normal State
• “VCC voltage” is between “over-discharge detection
voltage (Vuv)”, “over-charge detection voltage (Vov)”, 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.
• 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. Discharge is prohibited.
During discharging over-current state, VM pin is pulled
down to Vss by internal resistor (Rvmd).
(2) Over-charging State
• 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)”.
• “VCC voltage” is higher than or equal to “over-charge
detection voltage (Vov)” 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 (Vovr1)” for longer
than “over-charging release delay time (Tovr)”.
(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 “discharge over-current release
delay time (Tcocr)”.
• 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 (Vovr2) 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)”.
(6) 0 V Battery Charging
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.
• 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”.
• Release from Over-discharging State 1
(7) Reset State
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
• RST voltage is higher than or equal to high level input
voltage (VIH) for longer than the delay time of
factory−reset pulse (Tw_res).
This is the reset state, both CO and DO are low level
output. Charge and discharge are prohibited.

“VCC voltage” is higher than “over-discharge release
voltage2 (Vuvr1)” without charger for longer than
“over-charge release delay time (Tovr)”.
• Release from Reset State
RST voltage is lower than or equal to low level input
voltage (VIL) for longer than the delay time of factory
reset release pulse (Tw_res).
(4) Discharging Over-current State
• Under reset state, any protection doesn’t work. Under
both charging over current state and discharging over
current state, reset function doesn’t work.
• Discharge Over-current Detection 1
CS terminal is higher than or equal to “discharge
over-current detection voltage (Vdoc1)” for longer than
