2.2.4 PW1 Strobe Circuit Description
2.2.4.1 Charging Circuit
When UNREG power is supplied to the charge circuit and the CHG signal
becomes High (3.3V), the charging circuit starts operating and the main
electrolytic capacitor is charged with high-voltage direct current.
However, when the CHG signal is Low (0V), the charging circuit does not
operate.
