SGM41000
True Monolithic Li+/Li-Poly Battery Protector
Full Functions in Tiny Thin Package
GENERAL DESCRIPTION
The SGM41000 is designed for small Li+ or Li-Poly
rechargeable cells. This device has all circuits that are
typically used in battery protection, including charging
and discharging switches, detection and protection to
over-charging, over-discharging and over-current, empty
or battery under-voltage pre-charging, and shutdown
circuit for deep discharging.

ABSOLUTE MAXIMUM RATINGS
True Monolithic Li+/Li-Poly Battery Protector
Full Functions in Tiny Thin Package
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any other conditions beyond those indicated in the operational
section of the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
OVERSTRESS CAUTION

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. SGMICRO recommends that
all integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage
because very small parametric changes could cause the
device not to meet its published specifications.
Supply Voltage Range ..............................................0V to 8V
Battery Voltage Range ........................................2.6V to 4.5V
Charging Current (I

RECOMMENDED OPERATING CONDITIONS
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, specification or other related things if necessary
without notice at any time.
