Description
The NT1775 protects lithium-ion/lithium-polymer
rechargeable battery in the abnormal events of
over-charge, over-discharge, discharging over-current
and for a 3/4-cell lithium-ion/lithium polymer battery
pack.
If any of above abnormal conditions occurred.
NT1775 would turn off the MOSFETs to protect
battery.
NT1775 would enter power down mode when
over-discharge protection occurs to minimize the
current consumption.
The tiny package of 16 pin TSSOP is especially
suitable for the battery packs in portable devices.
