3. TECHNICAL BRIEF
3.8.3 Charging control
The PM6658 IC provides support circuitry for charging Li-ion batteries, utilizing as many as four MSM-
enabled charging techniques: trickle, constant current, constant voltage, and pulse. Battery voltage,
external supply voltage, and total detected current measurements are available to the MSM device
through the analog multiplexer. This allows the MSM device to monitor charging parameters, make
decisions, and control the charging process.
