ESD SENSITIVITY CAUTION

This integrated circuit can be damaged if ESD protections are

not considered carefully. SGMICRO recommends that all

integrated circuits be handled with appropriate precautions.

Failureto observe proper handlingand installation procedures

can cause damage. ESD damage can range from subtle

performance degradation tocomplete device failure. Precision

integrated circuits may be more susceptible to damage

because even small parametric changes could cause the

device not to meet the published specifications.

NOTES:

1. Evaluation at V_BAT= 4.5V.

2. The clamping may reach 10mA at an input voltage > 13V.

3. Test with a voltage regulated supply that has 2A current

limit and increase the voltage progressively for less than

1V/ms slope rate. Apply a voltage to the device under test

from 0V to given voltages.

True Monolithic Li-Ion/Polymer

SGM41100W

Battery Protector in Tiny Thin Package

DETAILED DESCRIPTION

The SGM41100W 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 (t_ODD),

the discharge path opens. The path closes again after

t_RETRYfor retrying. The SGM41100W keeps retrying until

the over-current condition is released or the battery

discharges to low when the SGM41100W turns into

battery under-voltage protection state.

Voltage Related Protections

When battery voltage reaches over-voltage threshold

(V_OV), 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 V_OVHYS

below the over-voltage threshold (V_OV).

During a charging condition if a charge over-current is

identified, the SGM41100W enters the locked-off state.

This state can be reset by charger removal (pack

removal).

In order to protect the battery from discharge

under-voltage status when battery voltage falls below

V_UVfor t_UVPDor V_SHDNinstantly, 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 V_UVHYSabove the V_UVthreshold.

Short-circuit protection: When discharge current

exceeds the over-current threshold, discharge path

disconnects instantly in t_OCSD, in order to protect the

battery from potential over-current stress. After this

disconnection, the SGM41100W stays in the locked-off

non-conducting state until being reactivated.

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 V_NOCHG: The charge path or

discharge path is open correspondingly when the

applied bias condition is settled.

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 is in the range of V_NOCHGto V_UV(if

there is such voltage gap): The path switch is on for

144ms (t_UVPD) in every 132ms 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 SGM41100Ws, a momentary current

surge may cause charge over-current protection in the

pack with the lower voltage. The higher voltage pack

could 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

c) Battery voltage above under-voltage threshold: In

this condition, the chip enters normal operation and

charge and discharge modes are allowed.

When battery voltage is between V_SHDNand V_NOCHG

there is about 150μs circuit settle time when a pulse

charge current may flow through.

,

voltage pack. After this discharge, both packs will

conduct.

When the battery voltage is in the range of 0.5V ~ 0.7V,

and the external voltage applied on the device is also

too low to start full operation, the charging current flows

through the path switch's body diode.

DETAILED DESCRIPTION (continued)

It is highly recommended that the packs should be

placed into a locked-open non-conducting state first (by

connecting PCKP 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.

of guided discharge path is desired for the equipment

case sealing air-gap discharge over the battery and

those connect to the battery closely.

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.

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

SGM41100W into a locked-off state after battery

attachment by momentarily shorting BYPS and PCKN.

Cautions for Evaluation Test

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 SGM41100W. 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.

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.

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

soldering/attaching the anode firstly in assembly (as the

short between cathode to ground will not cause

excessive surge).

Select Protection Parameters

Battery models from different vendors may be

customized for different applications. Consult the

battery vendor for protection limits for specific battery

model.

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 SGM41100W 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 V_OVis

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 I_OCis lower than

the charge current, the protection circuit also turns itself

into the locked-off state. In either V_OVor I_OC, 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 V_OVor I_OVevent, the battery will not be charged

even if the battery voltage is depleted.

The SGM41100W 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.

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
