MAX1894/MAX1924 Evaluation Kit
Note: Please indicate that you are using the MAX1894 or MAX1924 when contacting these component suppliers.
The MAX1894 EV kit is fully assembled and tested.
Follow these steps to verify board operation. Do not turn
on the power supply until all connections are completed.
• Current-limited 25V power supply (or Li+ charger)
• One voltmeter
• Four Li+ cells (2.3V to 4.35V)
Warning: Exercise caution when handling loose Li+ cells.
Obey all manufacturer guidelines for handling Li+ cells.
For test purposes, floating power supplies can be substi-
tuted for the Li+ cells.
