Description
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.
