一,产品概述(General Description)         
        JTM9901 is a spacing saving single chip lithium-ion/polymer battery protection IC.Integrating power MOSFET and only two external components makes the protection board highly compact. JTM9901 has full protection including over charging voltage protection, over discharging protection, over current protection, short protection and over temperature protection. The very low standby
current drains little current from the cell whilein storage. JTM9901 is available in 8 PIN SOP8_EPAD package

七,功能概述
Overcharge Protection
When the voltage of the battery cell exceeds the overcharge protection voltage (VOCV) beyond the
overcharge delay time (tOCV) period, charging is inhibited by turning off power MOSFET. The
overcharge condition is released in two cases:
1. The voltage of the battery cell becomes lower than the overcharge release voltage (VOCR)
     through self-discharge.
2. The voltage of the battery cell falls below the overcharge protection voltage (VOCV) and a load
is connected. When the battery voltage is above VOCV, the overcharge condition will not release
even a load is connected to the pack.

Overdischarge Protection
When the voltage of the battery cell goes below the overdischarge protection voltage (VODV)
beyond the overdischarge delay time (tODV) period, discharging is inhibited. Inhibition of
discharging is immediately released when the voltage of the battery cell becomes higher than
overdischarge release voltage (VODR).

Overcurrent Protection
When the discharging current becomes higherthan a specified Overdischarge Current and
beyond over discharge current delay time period, discharging is inhibited. Inhibition of
discharging is immediately released when theload is released or the impedance between EB+
and EB- is larger than 500kΩ. The JTM9901provides three over current detection levels (8A,
14A and 36A) with three over current delay time
