Detailed Description
The MAX17005/MAX17006/MAX17015 include all the
functions necessary to charge Li+, NiMH, and NiCd
batteries. An all n-channel synchronous-rectified step-
down DC-DC converter is used to implement a preci-
sion constant-current, constant-voltage charger. The
charge current and input current-limit sense amplifiers
have low-input offset errors (250μV typ), allowing the
use of small-valued sense resistors.
The MAX17005/MAX17006/MAX17015 use a new ther-
mally optimized high-frequency architecture. With this
new architecture, the switching frequency is adjusted
to control the power dissipation in the high-side
MOSFET. Benefits of the new architecture include:
reduced output capacitance and inductance, resulting in
smaller printed-circuit board (PCB) area and lower cost.
