Description

FULL DATA SHEET (PDF, 144kB) Download   E-Mail The MAX8568A evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX8568A and MAX8568B complete backup-management ICs for lithium and NiMH batteries. The MAX8568A EV kit can charge both NiMH and rechargeable lithium battery types; the EV kit default setting is for NiMH charging. Two on-board p-channel MOSFETs allow the evaluation of backup switchover from the primary source. Low-voltage backup cells can be stepped up by the on-chip synchronous-rectified step-up DC-DC converter, which has a default setting of 3.3V on the EV kit and is capable of 50mA output current. A secondary output provided by an on-chip LDO has a 2.5V output voltage for the MAX8568A and is capable of providing 10mA output current. When the main battery is connected, these two voltages are typically provided by a MAX1586/MAX1587 multi-output complete system power supply. The MAX8568A EV kit can also evaluate the MAX8568B. To evaluate the MAX8568B, order a free sample along with this EV kit.
