Figure 5 S-GOLDradio PMU circuit diagram
3.4.2. Charging
SM-POWER provides together with an external p-channel FET Siliconix NDC652P an external
AC-adapter a complete charge control function for charging of Li-Ion or Li-Ion-Polymer batteries. Either a
1-cell Li-Ion or Li-Ion-Polymer battery with 4.1, 4.2 or 4.4 Volts may be used.
