GROUND CONNECTIONS
LAYOUT AND EXTERNAL COMPONENTS
Important Information - The following layout guidelines and
required external components are critical to the proper opera-
tion of this motor drive.
Permanent damage will result to the motor drive if the user
does not make the following recommended ground con-
nections that will ensure the proper operation of the
hybrid.
The Vb, VLPI and logic ground returns are on pins 19, 22, and 26
(GND). The VSS connections for the output stage are on pins 1,
5, and 8 (VSS). To prevent damage to the internal drive cir-
cuitry, the differential voltage between GND (pins 19, 22, 26)
and VSS (pins 1, 5, 8) must not exceed ±3 V max, dc or peak.
This includes the combined voltage drop of the associated
ground paths and the voltage drop across RSENSE (see FIG-
URES 6 and 8).
For example, a value of RSENSE of 0.025
will give a voltage
drop of 0.375 V at 15 A. and allow enough margin for the voltage
drop in the ground conductors. Locate RSENSE 1IN. to 2IN. max-
imum from the hybrid. It is critical that all ground connections
be as short, and of lowest impedance, as the system allows.
C1 and C2 are 0.01
F power supply decoupling capacitors.
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 Tantalum capacitor or
clamping diode between VCC and the high power ground return.
