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.
In general, NT1775 can be restored to normal mode
after short-circuit or reversely charging is removed. To
avoid hiccup reaction as protection is activated due to
the serious short-circuit and reversely-charging
conditions, NT1775 may enter power down mode
sometimes. It can be awaked with charger
reconnection.
The tiny package of 16 pin TSSOP is especially
suitable for the battery packs in portable devices.
