n       FEATURES

be re-restored to normal working condition.

When VDD-side (VM-side)s voltage (current) is higher or lower than  the set value, the internal circuit will be determine whether works in the non-normal state  by the duration of the continued state.
when the duration of this state is in excess of the set time, SDC6073 will shut down the internal MOSFET,
cut off the charge and discharge circuit, and only under certain conditions are met, circuit will

is open,batteries works.

in the normal state,internal MOSFET

Under normal conditions, the SDC6073 open or close Internal MOSFET by detecting VDD and VM voltage or current to realize  the Purposes of monitoring the battery status.
IF VDD and VMs voltage,current are

overdischarge voltage protection, overdischarge current protection,
temperature protection, short- circuit protection (SDC6073 also
provide reverse battery protection and reverse battery charger
Protection); and  built-in construction of MOSFET can
effectively reduce production costs and improve circuit reliability .

SDC6073s application is extremely easy: the external circuit does not
need the MOSFET, only to connect two capacitors 0.1uF to provide that overcharge voltage protection, overcharge current protection,

the basis  of traditional battery protection; AND add detection chargers,  reverse polarity protection of batteries and chargers .Its a good choice to apply the ic to the  modern portable devices such as: mobile phones, digital cameras, single - section of the ideal rechargeable battery

The SDC6073 is a complex high-precision single-cell lithium ion/lithium-polymer battery protection IC. It intergrates MOSFET switch to the internal IC circuit in
