n APPLICATION HINTS

R1 and C1 will stabilize a supply voltage to the R5422Nxxxx. A recommended R1 value is less than 1kW.

A larger value of R1 leads higher detection voltage, makes some errors, because of shoot through current flowed in the

R5422Nxxxx.

R2 will stabilize a V- pin voltage. The resetting from over-discharge with connecting a charger possibly be disabled by larger

value of R2. Recommended value is less than 1 kW.

R1 and R2 can operate also as a part of current limit circuit against for setting cell reverse direction or for applying excess

charging voltage to the R5422Nxxxx, battery pack, while smaller R1 and R2 may cause a power consumption over rating of

power dissipation of the R5422Nxxxx and a total of 'R1+R2' should be more than 1kW.
