supplies generally have a quiescent current draw of a few
milliamperes, which is far more than the microamperes used
by the MIC2561. The charge pump of Figure 5 provides this
low current, using about 100
μ
A when enabled. When V
PP OUT
= 12V is selected, however, the on-demand V
PP
generator
must be used, as this charge pump cannot deliver the current
required for Flash memory programming. The Schottky diode
may not be necessary, depending on the configuration of the
on-demand +12V generator and whether any other loads are
on this line.
