ZXBM2001
ZXBM2002 ZXBM2003
When driving fans with bipolar transistors, at higher
voltages it may be necessary to provide extra noise
protection by the addition of a diode from the driver
collector to Gnd on each phase. This prevents negative
voltage excursions from the windings affecting
operation. See Figure 3 right, showing the placement
of these diodes. It should be noted that these are not
required for the MOSFET solution in Figure 2 as the
diodes are inherent in the MOSFET structure.
Zetex provide a variety of suitable power transistors for
using with the ZXBM200x series of 2-phase DC
brushless motor pre-drivers and suitable devices
sufficient for a range of applications are given in the
following table.
