DESCRIPTION

The EV26124-R-00A is an evaluation board for

the MP26124, a high-performance, 4-cell, Li-ion

battery switching charger with a built-in internal

power MOSFET.

The EV26124-R-00A achieves 1A of charge

current over a wide input supply range. The

charge current can be programmed by sensing

the current through an accurate sense resistor.

The MP26124 regulates the charge current and

full-charge voltage using two control loops to

achieve a highly accurate CC charge and CV

charge.

The MP26124 integrates trickle charge, auto-

recharge, and charger timer functions.

Full

protection

features

includes

thermal

protection, battery temperature monitoring, and

protection. The IC also indicates AC adapter

power good and charge status to the system.
