MAX17435 datasheet

Description :

General Description
The  MAX17435/MAX17535  integrated  multichemistry battery-charger  ICs  simplify  construction  of  accurate and  efficient  chargers.  The  MAX17435/MAX17535
provide SMBusK-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 10mIsense resistors. The
MAX17435/MAX17535  fixed-inductor  ripple  architecture significantly reduces component size and circuit cost.
