Technical Notes
R1 and C1 will stabilize a supply voltage to the NCP802. A recommended R1 value is less than 1.0 k A larger value of R1
leads to higher detection voltages. There may also be voltage detector errors from shoot through current into the NCP802.
R1 and R2 can also help current limit the circuit against reverse charge or a charger with excess charging voltage applied to
the NCP802 battery pack. Smaller R1 and R2 values may cause excessive power consumption over the specified power
dissipation rating. Therefore, the total value of R1
R2 should be equal to or more than 1.0 k
large value of R2, it might not be possible to release from undervoltage by connecting a charger. The recommended R2 value
is equal to or less than 30 k
.
