• Manufacturer: Maxim Integrated
• Series: MAX1894, MAX1924r

Jumper JU3 selects the logic state of the control pin of
the MAX1894. To force a logic high on the control pin,
install a shunt across pins 1 and 2 of JU3. To force a
logic low on the control pin, install a shunt across pins
2 and 3 of JU3. The control mode can also be driven by
an external µC. Remove the shunt from jumper JU3 and
connect the output of the µC to the CTL pad. See Table
3 for shunt positions.

Jumper JU5 selects between the 3-cell and the 4-cell
battery pack applications for the MAX1894 EV kit. The
MAX1894 EV kit is set at the factory for 4-cell applica-
tions. For 3-cell battery pack applications, install a
shunt across JU5, and replace U1 with the MAX1924V.
See Table 5 for shunt positions.
