The APL3200 charges a single-cell Li+ battery from both
USB and AC adapter sources. It also includes battery-
to-input power switchover, therefore, the system can be
powered directly from the power source rather than from
the battery.
In its simplest application, the APL3200 doesn’t need
external MOSFET or diodes and accepts input voltages
up to 6.5V; however, DC input over-voltage protection up
to 18V can be added with a single SOT PFET.
On-chip thermal limiting simplifies PC board layout and
allows optimum charging rate without the thermal
limits imposed by worst-case battery and input voltage.
When the APL3200 thermal limit is reached, the charger
does not shut down but simply reduces charging current.
Ambient or battery temperature can be monitored with
an external thermistor. When the temperature is out of
range, charging pauses.
Other features include STAT 1 and STAT 2 outputs
indicating various charge status. DC power-OK (DCOK),
USB power-OK (UOK), and poweron (PON) outputs
indicate when valid power is present. These outputs drive
logic or power-selection MOSFETs to disconnect the
charging sources from the load and to protect the APL3200
from overvoltage. The APL3200 doesn’t contain logic for
communication with the USB host. It must receive
instructions from a local microcontroller. The APL3200
is available in 16-pin 5mmx5mm QFN and 4mmx4mm
TQFN packages and operates over the -40°C to +85°C
temperature range.
