10.1.2 Charging Application Circuit
Fig.2 FS3861 Application Circuit
The Fig.2 shows the typical FS3861 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 as the pass transistor realizes the control of C-C and/or C-V mode current/voltage regulations.
