The EV2615-Q-00A is an evaluation board for the MP2615, a switching charger for 1- or 2-cell Lithium-ion or Lithium-polymer batteries, packed with built-in power MOSFETs. It is able to achieve up to 2A of charge current, which can be programmed via an accurate current-sense resistor over the whole input range.
The MP2615 regulates the charge current and full battery voltage using two control loops to realize high accuracy constant current (CC) charge and constant voltage (CV) charge. Thanks to the COT mode control, a 99% duty cycle can be achieved when the battery voltage is close to the input voltage to keep the charge current always at a relatively high level.
Battery temperature and charging status are always monitored for each condition. Two status monitor output pins are provided to indicate the battery charging status and input power status. The MP2615 also features internal reverse blocking protection.
