The EV26123-R-00A is an evaluation board for the MP26123, a high-performance 2-cell or 3-cell Li-ion battery switching charger with a built-in, internal power MOSFET.
The EV26123-R-00A achieves up to 2A of charge current across a wide input supply range. The charge current can be configured by sensing the current through an accurate sense resistor.
The MP26123 regulates the charge current and full-charge voltage using two control loops to achieve a high-accuracy constant current (CC) charge and constant voltage (CV) charge.
Fault protections include timeout control, full battery termination control, thermal protection, battery temperature monitoring, and protection. The board also indicates AC adapter power good, as well as the system’s charge status.
