The supply voltage (VDD) to this IC is stabilized by R1 and C1. Moreover, R1 and R2 act as the current restriction
resistances at the time of reverse-connecting a charger, or at the time of connecting a charger which outputs the voltage
exceeding the absolute maximum rating of this IC. Be sure to connect these components.
If the value of R1 is too large, the over-charge detection voltage will become high due to the current consumption of this
IC. 330
Ω is recommended.
If the value of C1 is too small, this IC may be in a shutdown state at the time of the discharge over-current or the load
short-circuiting. 0.1
μF is recommended.
Use the value within the limits shown in the table about the value of R2. In order to reduce the current at the time of
reverse-connecting a charger, we recommend to choose R1 and R2 so that the sum total of resistance values is more than
4k
Ω. The recommended value of R2 is 3.9kΩ.
Note 1 : The connection diagram and each value of external components shown above are just recommendation. Including
a battery and FETs, determine the circuit after sufficient evaluation about your actual application.
Note 2 : The IC is susceptible to static electricity and some pins are easily damaged by it. Handle the IC carefully.
