True Monolithic Li-Ion/Polymer
SGM41100A
Battery Protector in Tiny Thin Package
DETAILED DESCRIPTION
The SGM41100A monitors voltage and current applied
on battery cell connected between PCKP and BATN,
and opens the connection between battery and pack
terminal with its internal switches when a fault condition
is detected.
Current Related Protections
When discharge over-current condition occurs and
keeps for discharge over-current detection delay (tODD),
the discharge path opens. The path closes again after
t
RETRY for retrying.
During a charging condition if a charge over-current is
identified, the SGM41100A enters the locked-off state.
This state can be reset by charger removal (pack
removal).
Voltage Related Protections
When battery voltage reaches over-voltage threshold
(VOV), the charge path is open-circuit. The path closes
again when the charger voltage is lower than battery
voltage and the battery voltage falls back about VOVHYS
below the over-voltage threshold (VOV).
Short-circuit protection: When discharge current
exceeds 4 times or 3 times of the over-current threshold
(4-times for _03/_05 options, 3-times for _09 option),
discharge path disconnects instantly in tOCSD, in order to
protect the battery from potential over-current stress.
After this disconnection, the SGM41100A stays in the
locked-off non-conducting state until being reactivated,
or leakage condition pulls the PCKN potential off the
PCKP's towards to the BATN potential when the load is
fully detached off.
In order to protect the battery from discharge
under-voltage status when battery voltage falls below
VUV for tUVPD or VSHDN instantly, the discharge path is
open-circuit, the device enters into shutdown with only
very low resistive leakage flowing into it, which helps to
keep the battery from harmful exhausted condition as
long as possible. The path closes again when a
charging supply is applied and the battery voltage rises
to about VUVHYS above the VUV threshold.
Burst load outrush: In many systems, overload
conditions will occur momentarily. The device allows for
this short duration discharge condition by allowing the
discharge path to remain closed even after a discharge
over-current is detected for duration of discharge
over-current detection delay.
Charge an exhausted battery: While the battery is
over-discharged the battery could be in the following
states.
a) Battery voltage below 0.2V: Both charge and
discharge paths are open-circuit.
When a charge over-current condition is identified, and
after charge over-current detection deglitch, the charge
path is cut off. The device restores to the conducting
state when the PCKP to PCKN voltage drops about
3mV lower than the battery voltage.
b) Battery voltage in the range of 0.2V to VSHDN: The
battery is charged through the MOSFET body diode.
c) Battery voltage in the range of VSHDN to VUV: The path
switch is on for 144ms (tUVPD) in every 130ms and off
for 2ms when charge current flows through the body
diode. During this period, the charger will see the
terminal voltage steps up/down.
Parallel battery packs: When paralleling two battery
packs utilizing SGM41100As, a momentary current
surge may cause charge over-current protection in the
pack with the lower voltage. The higher voltage pack
can enter a discharge over-current protection. The
charge over-current or discharge over-current protection
resets only after the higher voltage battery pack
discharges to a voltage slightly lower than the lower
voltage pack. After this discharge both packs will
conduct.
d) Battery voltage above under-voltage threshold: In this
condition, the chip enters normal operation and
charge and discharge modes are allowed.
It is highly recommended that the packs should be
placed into a locked-open non-conducting state first (by
connecting BYPS to PCKN momentarily) before being
paralleled to avoid current overstress. When a charge
supply is applied to the paralleled packs, the
locked-open state will release.

DETAILED DESCRIPTION (continued)
Battery delivery state: It is recommended to deliver a
battery pack in a locked-off non-conducting state to
avoid unintentional shorting during production handling
or transportation. The circuit of Figure 1 places the
SGM41100A into a locked-off state after battery
attachment by momentarily shorting BYPS and PCKN.
Caution about ESD damage to the battery: The
battery pack might be the biggest element in equipment
and induce much during an ESD event. Careful design
of guided discharge path is desired for the equipment
case sealing air-gap discharge over the battery and
those connect to the battery closely.
Connecting a 220nF capacitor clapping between BATN
and PCKN may place the device into conducting state,
which might couple enough charge for making enough
voltage difference between PCKN and PCKP for over
about 1.3V. The voltage difference is the dividing result
of the clapping capacitance and the load resistance and
capacitance. The 220nF capacitance is recommended for
no load condition.
Caution on electrochemical corrosion: As a battery
can apply potential over the electrodes continuously
and cause electrochemical corrosion, the corrosion
product may spread in the hollow beneath a surface
mount device and cause leakage. Moisture-proof
coating is recommended, especially when using
compact devices.
Cautions for Evaluation Test
Pack activation: In order to release the pack from
locked-off state and to place it into a conducting state,
apply a charging input, or connect PCKN to BATN
momentarily when there is no high load capacitance.
Some types of electronic load simulators may have
excessive inrush current, and some BPM testers may
have voltage transition surges, which may trigger the
protection of the SGM41100A. Careful attention is
required for doing such evaluations with these kinds of
equipment. External voltage and current limits within
the conditions specified in the Absolute Maximum
Ratings section of this datasheet are required.
Caution: The battery short or load side terminal short
outside the protection circuit′s loop during battery
attaching may cause excessive high surge current and
excessive high current-breaking voltage surge, which
may cause damage or degrade the life duration of
battery and protection circuit. It is recorded that the
accidental anode to ground plane shorting causes
heavy surge, which can actually be avoided by leaving
enough clearance around the anode pad on PCB or

Battery models from different vendors may be
customized for different applications. Consult the
battery vendor for protection limits for specific battery
model.
soldering/attaching the anode firstly in assembly (as the
short between cathode to ground will not cause
excessive surge).
Parameters for the protection circuit and of the charger
circuit affecting same variables should be set for proper
charge or discharge protection sequence. For example,
the over-voltage threshold of the battery should be
50mV ~ 100mV higher than constant voltage threshold
of the charger.
Surge, ESD and Reversed Attachment
The SGM41100A absorbs voltage surge applied
between PCKP and PCKN, by passing the surge
current through its switch and the battery. Surge may
occur when attaching the pack or battery cell.
Cautions on parameter misalignment: If the VOV is
lower than the full charge voltage of the battery charger,
the protection circuit cuts off the battery charge path
before the battery is fully charged, and turns into the
non-conductive locked-off state; if the IOC is lower than
the charge current, the protection circuit also turns itself
into the locked-off state. In either VOV or IOC, the charger
input should be removed and then reapplied for
activating the protection circuit from the locked-off state
to the conducting state. If the charger is not removed
after a VOV or IOV event, the battery will not be charged
even if the battery voltage is depleted.
The SGM41100A survives either if a cell is placed in
reverse or a charge input is attached in reverse, but not
both at the same time. Any of these reverse
attachments, short circuits, inrush surges and outrush
will cause overstress. Do not test those cases in normal
production inspection, as this kind of test itself may
cause performance degradation or even damage the
device.
