NT1775-LNGQ1中文资料新德科技数据手册PDF规格书

描述 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.
