... MOSFETs. The charging and discharging processes can be operated normally. This is called the normal condition. Note: When a battery is connected to FS326 for the first time, it may not enter the normal condition (dischargeable may not be enabled). In this case, short the CSI and VSS pins or connect a charger to restore to the normal condition ...

... By forcing DS to VDD, the delay time of the overcharge and overdischarge can be reduced to within 50ms; therefore, testing time of protector circuit board can be reduced.1.6M Ω pull down resistor is connected between DS pin and VSS internally. DS pin should be left open or connected to VSS in the actual application. Rev. 1.9 FS326 11/20 ...
