______________________________________________________________________________________
The voltage-slope, fast-charge termination circuitry
might become disabled if attempting to charge a
different number of cells than the number programmed.
The switching frequency (nominally 30kHz) can be
decreased by increasing the value of the capacitor
connected between CC and BATT-. Make sure that
the two capacitors connected to the CC node are
placed as close as possible to the CC pin on the
MAX712/MAX713 and that their leads are of minimum
length. The CC node is a high-impedance point, so do
not route logic lines near the CC pin. The circuit of
Figure 19 cannot service a load while charging.
Order the MAX713SWEVKIT-SO for quick evaluation of
the MAX712/MAX713 in switch-mode operation. For
more information on switch-mode operation and
ordering information for external components, order the
MAX713EVKIT data sheet.
Battery-Charging Examples
Figures 13 and 14 show the results of charging 3 AA,
1000mAh, NiMH batteries from Gold Peak (part no.
GP1000AAH, GP Batteries (619) 438-2202) at a 1A rate
using the MAX712 and MAX713, respectively. The
Typical Operating Circuit
is used with Figure 9a’s
