General Description
Features
The MAX17435/MAX17535 integrated multichemistry
battery-charger ICs simplify construction of accurate
and efficient chargers. The MAX17435/MAX17535
provide SMBus K -programmable charge current, charge
voltage, input current limit, relearn voltage, and digital
readback of the IINP voltage. The MAX17435/MAX17535
utilize a charge pump to control the adapter selection
n-channel MOSFETs when the adapter is present. When
the adapter is absent, the charge pump is shut down and
a p-channel MOSFET selects the battery.
The MAX17435/MAX17535 provide up to 7A of charge
current to 2, 3, or 4 lithium-ion (Li+) cells in series. The
charge current, and input current-limit sense amplifiers have
low offset errors and can use 10m I sense resistors. The
MAX17435/MAX17535 fixed-inductor ripple architecture
significantly reduces component size and circuit cost.
The MAX17435/MAX17535 provide a digital output that
indicates the presence of the adapter, an analog output
that indicates the adapter or battery current, depending
upon the presence or absence of the adapter, and a
digital output that indicates when the adapter current
exceeds a user-defined threshold.
The MAX17435 switches at an 850kHz frequency and the
MAX17535 switches at 500kHz.
