The MAX1538 EV kit features an additional header (J1)
that can be connected to a user-provided computer
interface. When using this interface, disable the manual
interface (switches and LEDs) by cutting the traces at
jumpers JU3, JU4, and JU5. Also disable the on-board
MAX1615 power supply by cutting the traces at jumpers
JU1 and JU2. See
Eight MOSFETs are not required if the application does
not use specific features of the MAX1538. MOSFET P1,
P4, or both, may be removed depending on what fea-
tures are required.
If the relearning mode of the MAX1538 is not required,
remove MOSFET P1 and short the pads of resistor R17.
When using a buck-converter battery charger (i.e., the
AC-adapter voltage is greater than the charge voltage
of the charger), remove MOSFET P4 and short the pads
of resistor R18.
