GROUND CONNECTIONS
LAYOUT AND EXTERNAL COMPONENTS
Important Information - The following information regarding lay-
out guidelines and required external components is critical to the
proper operation of these motor drives.
External connections can be easily made to the hybrid by any of
the following methods:
Solder a wire around each pin.
Use a printed circuit board with a cutout that will enable the
printed circuit board to slide over the pins.
Permanent damage will result to the motor drive if the user does
not make the following recommended ground connections that
will ensure the proper operation of the hybrid.
The Vb and logic grounds are on pins 7 and 18 (GND). The Vss
connections for the output stage are on pins 1 and 4 (Vss). To
prevent damage to the internal drive circuitry, the differential volt-
age between GND (pins 7, 18) and Vss (pins 1, 4) must not
exceed ±3 V max, dc or peak. This includes the combined volt-
age drop of the associated ground paths and the voltage drop
across Rsense (see FIGURE 12).
For example, a value for
Rsense of 0.025 W will give a voltage drop of 1.25 V at 50 A and
allow enough margin for the voltage drop in the ground conduc-
tors. Locate Rsense 1" - 2" maximum from the hybrid. It is criti-
cal that all ground connections be as short, and of lowest imped-
ance, as the system allows.
C1 and C2 are 1 mF, 10 V ceramic capacitors that provide a low
ac impedance between each Vss pin and GND. You must use
one capacitor for each Vss pin-to-GND connection (total of two
capacitors in all). These capacitors are independent of the type
of drive scheme used. Since placement of these capacitors is
critical, place these capacitors across the hybrid, if possible.
Please note, on FIGURE 12, that C1 and C2 must go directly
from terminal to terminal on the hybrid — do not daisy chain
along the ground return.
C3 and C4 are the 0.1 mf ceramic bypass capacitors that sup-
press high frequency spiking. The voltage rating should be 2x
the maximum system voltage. These capacitors should be locat-
ed as close to the hybrid as possible.
Care must be taken to control the regenerative energy produced
by the motor in order to prevent excessive voltage spiking on the
Vcc line. Accomplish this by placing a capacitor or clamping
diode between Vcc and the high power ground return.
