MONOLITHIC POWER SYSTEMS (MPS) EV2615B-Q-00A

EV2615B-Q-00A is a 18V, 2A, 4.03V or 3.93V VBATT, single-cell, lithium-ion battery charger evaluation board. It is an evaluation board designed to demonstrate the capabilities of the MP2615B, monolithic switching charger with integrated power MOSFETs designed for single-cell lithium-ion or lithium-polymer batteries. The charge current can be configured via an accurate current-sense resistor. The MP2615B regulates the charge current (ICHG) and battery voltage (VBATT) with two control loops to enable high-accuracy constant current (CC), constant voltage (CV) charging. Constant-off-time (COT) control can achieve 99% duty cycle once VBATT reaches the input voltage (VIN) to maintain a high ICHG. 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. Typical application includes smartphones, portable handheld solutions, portable media players.
