The FS3862 is a low-cost high-performance Li+
single-cell 4.2v/4.1v battery charger control IC which
includes all the required constant-current and
constant-voltage regulations of charge functions
addressed for linear charger mode operations in
typical four phases: pre-charging conditioning,
constant current, constant voltage, and charge
terminations (usually based on the minimum current
reached). The maintenance re-charge (or called
post-charge stage) proceeds if the full-charged
battery voltage is once again lower than the desired
full-capacity voltage because of consumptions of its
capacity which occurs either at the battery’s internal
voltage drop across its terminals, or at the use of the
battery.
This chip with built-in 8-bit RISC-type MCU with
1K-word OTP PROM and 64-Byte data RAM
employs a minimum numbers of external transistor
and passive resistor & capacitor devices to fulfill
complete charger implementations at cost-effective
solutions.
The available 16-pin SSOP-16 package is offered for
balanced area and cost effective requirements for
size-sensitive applications.
The FS3862 is suitable for the control of charge
sequences of a variety of portable battery-powered
applications, such as cellular phone’s travel and
base charger devices, digital camera, digital-video
camcorder (DV), MP3 player ,etc.
