The EV2703-RP-00A is an evaluation board designed to demonstrate the capabilities of the MP2703, a 26V, 1A, highly integrated linear charger for Li-ion or Li-polymer batteries with battery diagnostics.

The MP2703 has a dedicated ISET pin to set the charge current (I_CC) by connecting a resistor from this pin to ground. The MP2703 also has a minimum input voltage (V_IN) limit to reduce I_CC when the input power is overloaded.

The MP2703 integrates a battery diagnostic function. The BATTSNS pin provides an output proportional to the real battery voltage (V_BATT), which can be directly delivered to the external analog-to-digital converter (ADC) input to measure V_BATT. In addition, an internal dummy load can be controlled to discharge the battery. An external microcontroller (MCU) can detect the battery impedance by measuring V_BATT using the discharge function.

The MP2703 supports a fully customizable JEITA profile with configurable temperature windows and actions.

The EV2703-RP-00A supports an operating voltage up to 6V, and an absolute maximum V_IN up to 26V.
