3. Intrinsic Diode Losses (Pd)
Pd= Id (avg) x Vd (avg)
Id(avg) = [(IOB + IOA) / 2] / 2 = [(7 A + 3 A) / 2] / 2 = 2.5 A
Pd = 2.5 A x 1.25 V
Pd = 3.125 Watts
TRANSISTOR POWER DISSIPATION ( PQ)
To calculate the maximum power dissipation of the output tran-
sistor as a function of the case temperature use the following
equation. (Reference FIGURE 8 to ensure you don’t exceed the
maximum allowable power dissipation of each transistor.
PQ = Pc + Ps + Pd
TOTAL HYBRID POWER DISSIPATION (PTOTAL)
To calculate Total Power dissipated in the hybrid use:

P
TOTAL= ∑ [ PQi ] where i = each transistor
i=1
LAYOUT AND EXTERNAL COMPONENTS
Important Information - The following layout guidelines and
required external components are critical to the proper
operation of these motor drives.
Permanent damage will result to the motor drive if the user
does not make the following recommended ground connec-
tions that will ensure the proper operation of the hybrid.
The V+ and logic grounds are on pins 5,18, and 19 (GND). The
Vss connections for the output stage are on pins 26-28, 33-35
and 40-42 (VSS). To prevent damage to the internal drive cir-
cuitry, the differential voltage between GND and VSS 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 FIGURE 9). For example, a value for
Rsense of 0.1
will give a voltage drop of 1.00 V at 10 A and
allow enough margin for the voltage drop in the ground conduc-
tors. Locate Rsense 1" - 2" maximum from the hybrid. It is crit-
ical that all ground connections be as short, and of lowest
impedance, as the system allows.
C1, C2, and C3 are 0.1
F ceramic bypass capacitors that sup-
ply high frequency spiking. The voltage rating should be 2x the
maximum system voltage. These capacitors should be located as
close to the hybrid as possible. Please note, on FIGURE 9, that
C1, C2, and C3 must go directly from terminal-to-terminal on the
hybrid - do not daisy chain along the power ground return.
C4 and C5 are 0.01
F, 50 V ceramic capacitors for power sup-
ply decoupling. Locate as close to the hybrid as possible. CC is
a 1
F, 20% capacitor (either polarized or nonpolarized). If a
polarized cap is used, the positive terminal must be connected
to pin 48 of the hybrid. Voltage rating should be 2x the maximum
system voltage.
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 high power ground return.
