What if our SCP will not fit in your application?

Lower current solution

In case you would like to use our SCP. However it has to cut under the double rated current In this case you can add a current detection circuit and a resistor. The current detection circuit will detect the lower current and turns the FET

• n. The SCP can cut at any time you want.

High voltage solution (VDR)

Voltage Divide Resistance

High voltage solution (SVS)

2nd-IC will check all the cells SCP model for 5 cells

Suitable Voltage Supply

FET line for 5 cells. In case of overvoltage: FET turns ON and the suitable voltage will be suplied through the heather

High current solution (Parallel)

Parallel Solution
