Descriptions
NT1792 is an accurate secondary battery protection
IC for all 4-cell battery packs. A programmable
external delay circuit and an internal delay circuit are
both embedded for overcharge detection delay time.
The comparators with a precise reference are built on
each VCx pin detecting cell voltages. If one of the cell
voltage goes greater than the overcharge detection
voltage, NT1792 starts discharging the external delay
capacitor C
CD
until the voltage of CD pin is lower than
1.11V. After that, the Out pin inverses from a low
state to a high state to blow the fuse.
