MP2710 4.35-5.5V, 500mA Li-Ion Battery Charger WLCSP-9

The MPS MP2710 is a Li-Ion Battery Charger. It operates from a 4.35 V to 5.5 V input and is rated for 500 mA. It is supplied in a WLCSP-9 package.

The MP2710 is a highly integrated, single-cell, Li-ion/Li-polymer battery charger with system power-path management (PPM) for space- restricted, portable applications.

Design Notes

Charge current accuracy depends on the sense resistor tolerance, so use a 1% or better part and keep its traces Kelvin-connected.
Wire the NTC input for JEITA profile control if the pack is charged over temperature.
Set the input current limit to what the adapter can actually deliver; a limit above the adapter rating causes the input rail to collapse mid-charge.
Termination current and recharge threshold dominate cycle life in shallow-cycling products.
