FS3862
Fig.8-4 FS3862 P-MOS Application Circuit
The Fig.8-2 shows the typical FS3862 application circuit used at base or travel charger devices of a variety of
cellular phone and other portable devices. The above application circuitry shows the chip connected with an
one-cell Li+ 4.2v battery, which features battery ID (at the VBATID input pin) and temperature sense output (at
TS pin) for relevant controls. Interface to external host is optional at the general I/O bus pins with connections to
the host side which commands the base charger with monitor facilities to control the charger operations. The
use of PNP or PMOS (Fig.8-4) as the pass transistor realizes the control of C-C and/or C-V mode
current/voltage regulations.
