1. 介绍Introduction
LTO8-10SA 是力通威公司专门针对电动工具
8~10 串电池包而设计的保护板方案；可适用不同化学
性质的锂电芯，如锂离子、锂聚合物、磷酸铁锂等。
保护板预留了一个SMBUS 通讯接口，可用来设
置各种保护电压、电流等参数，灵活性很强。保护板
带载能力强，持续电流最大可达20A。
LTO8-10SA for a battery pack of 8~10 cells in
series is a battery protection solution of LTW’s,
which is designed for the application in power tools.
It can be used for cells of different chemistry, for
example Li-ion, Li-Polymer, LiFePO4 and so on.
A SMBus interface is kept on the pack, which
may be used to set parameters very conveniently
such as protect voltage, protect current , etc, The
pack can support a load with very large current, in
addition that the continuous current may be up to
20A.
