The EV2615B-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP2615B, a monolithic switching charger with integrated power MOSFETs designed for single-cell lithium-ion or lithium-polymer batteries. It can achieve up to 2A of charge current (I_CHG) across a 4.5V to 18V input voltage (V_IN) range. I_CHG can be configured via an accurate current-sense resistor.

The MP2615B regulates I_CHG and the battery voltage (V_BATT) with two control loops to enable high-accuracy constant current (CC) and constant voltage (CV) charging.

Constant-off-time (COT) control can achieve 99% duty cycle once V_BATT reaches V_IN to maintain a high I_CHG. The battery temperature and charging status are monitored. Two status-monitoring output pins (ACOK and CHGOK) are provided to indicate the battery charge status and input power status. The MP2615B also features internal reverse-blocking protection.

The MP2615B is available in a QFN-16 (3mmx3mm) package.
