When the external power supply is used for VG, apply power in the order from VCC, through VG, to each BAT. For each BAT, turn ON power supply after complete rising of VCC and VG voltages. 2. Each power supply must be stabilized by inserting a capacitor to GND to prevent entry of ripple and noise. In particular, the capacitor of sufficient capacitance must be used for the output because the large current flows here. The capacitor to be inserted in each power supply should be installed as near as possible to the IC pin.
