SGM41100V

True Monolithic Li-Ion/Polymer

Battery Protector in Tiny Thin Package

GENERAL DESCRIPTION

FEATURES

The SGM41100V is designed for primary protection of

Li-Ion/polymer rechargeable cells. The product integrates

all the protections required for safe operation of polymer

rechargeable cells. The device is packaged in a tiny and

thin package. Its small solution size leaves more space

for fitting the battery cell into a given cavity for small size

wearable devices.

● Ultra-Compact Protection Solution

● Pass Resistance: 42mΩ (TYP)

● Operation Current: 1.1μA (TYP)

● Factory Programmable OVP Threshold Options

4.20V to 4.575V with 0.025V per Step

● Charge/Discharge Over-Current Protection

3 Thresholds Combination Options

● Battery Under-Voltage Protection

2.6V/2.7V/2.8V/3.0V Options

The SGM41100V integrates all the protections and the

required low on-resistance disconnect switch on one

die. The protection features include charge and

discharge protection, detection and protection of a cell

in charge over-voltage, charge over-current, discharge

under-voltage and discharge over-current. Charge and

discharge are prohibited when the battery is lower than

the certain voltage and under-voltage. The product also

disconnects the battery pack in the case of deep

discharge.

● 50nA Deep Discharge Shutdown

● Input Surge Clamping

● Input Over-Voltage Safe

● Load Short-Circuit Safe

● Reverse Polarity Battery Safe

● Input Reversed-Attaching Safe

● Battery Pack Paralleling Safe

● Locked-Off for Delivery/Assembly

● Available in a Green UTDFN-1.5×2-6L Package

The SGM41100V operates in -40℃ to +85℃ temperature

range, and is in a thin and low profile UTDFN-1.5×2-6L

package. This package with a nominal height of 0.5mm

is convenient for small cell packing designs.
