NT1775中文资料Protection ICs数据手册Neotec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.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.
