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, autorecharge, 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.
