MAX8903AEVKIT

Evaluation Kit for the MAX8903A, MAX8903B, MAX8903C, MAX8903D, and MAX8903Y


Please check latest availability status for a specific part variant.

Description

The MAX8903A evaluation kit (EV kit) is a fully assembled and tested circuit board for evaluating the 2A, 1-cell Li+ DC-DC battery charger. The EV kit charges a single-cell lithium-ion (Li+) battery from a DC input (AC adaptor) or a USB 100mA/500mA source and provides system power from the DC input, USB input, or battery. Battery charge current and SYS current limit are independently set. Charge current and DC converter output current limit can be set up to 2A, respectively. The USB input current can be set to 100mA or 500mA and USB suspend mode is also supported. Power not used by the system is available to charge the battery.

The EV kit comes standard with the MAX8903A installed. However, the EV kit can also be used to evaluate the MAX8903B–MAX8903E and MAX8903Y by replacing the MAX8903A (U1) with the preferred IC.
