General Description
The MAX17005B/MAX17006B/MAX17015B are high-fre-
quency multichemistry battery chargers. These circuits
feature a new high-frequency current-mode architecture
that significantly reduces component size and cost. The
charger uses a high-side MOSFET with n-channel syn-
chronous rectifier. Widely adjustable charge current,
charge voltage, and input current limit simplify the con-
struction of highly accurate and efficient chargers.
The charge voltage and charge current are set with
analog control inputs. The charge current setting can
also be adjusted with a PWM input. High-accuracy cur-
rent-sense amplifiers provide fast cycle-by-cycle cur-
rent-mode control to protect against short circuits to the
battery and respond quickly to system load transients.
In addition, the charger provides a high-accuracy ana-
log output that is proportional to the adapter current. In
the MAX17015B, this current monitor remains active
when the adapter is absent to monitor battery dis-
charge current.
The MAX17005B charges three or four Li+ series cells,
and the MAX17006B charges two or three Li+ series
cells. The MAX17015B adjusts the charge voltage set-
ting and the number of cells through a feedback resis-
tor-divider from the output. All variants of the charger
can provide at least 4A of charge current with a 10m Ω
sense resistor.
The charger utilizes a charge pump to control an n-channel
adapter selection switch. The charge pump remains
active even when the charger is off. When the adapter
is absent, a p-channel MOSFET selects the battery.
The MAX17005B/MAX17006B/MAX17015B are avail-
able in a small, 4mm x 4mm x 0.8mm 20-pin, lead-free
TQFN package. An evaluation kit is available to reduce
design time.
