The MAX1679 controls the GATE slew rate. The layout is
not as sensitive to noise as a high-frequency switching
regulator. In addition, since the cell voltage is sensed
both during and between high-current pulses, the sys-
tem is insensitive to ground drops. However, Maxim rec-
ommends establishing good grounding areas and large
traces for high-current paths.
