Operation 
VD1/Over-Charge Detector 
The VD1 monitors VDD pin voltage. When the 
VDD voltage crosses over-charge detector 
threshold Vdet1 from a low value to a value 
higher than the Vdelt1, the VD1 can sense 
over-charging and an external charge control 
Nch-MOS-FET turns to “OFF” with Cout pin

being at “L”. 
An output delay time for over-charge detection 
can be set by an external capacitor C3 
connecting the VSS pin and Ct pin. The external 
capacitor can make a delay time from a moment 
detecting over-charge to a time output a signal
