further slow switching edges and prevent transient

to the following equations:
The MAX1736 controls the GATE slew rate; conse-
quently, PC board layout is not as sensitive to noise as
a high-frequency switching regulator. In addition, since
cell voltage is sensed both during and between high-
current pulses, the system is insensitive to ground
errors. However, Maxim recommends maintaining large
ground area and large traces for high-current paths.
Refer to the MAX1736EVKIT for a recommended layout
example.
