Separate Logic and Power Grounds
The IRS26302DJ has separate logic and power ground pin (V
noise problems that can occur in power conversion applications. Current sensing shunts are commonly used in many
applications for power inverter protection (i.e., over-current protection), and in the case of motor drive applications, for
motor current measurements. In these situations, it is often beneficial to separate the logic and power grounds.

Tolerant to Negative V
A common problem in today’s high-power switching converters is the transient response of the switch node’s voltage
as the power switches transition on and off quickly while carrying a large current. A typical 3-phase inverter circuit is
shown in Figure 27; here we define the power switches and diodes of the inverter.
If the high-side switch (e.g., the IGBT Q1 in Figures 28 and 29) switches off, while the U phase current is flowing to
an inductive load, a current commutation occurs from high-side switch (Q1) to the diode (D2) in parallel with the low-
side switch of the same inverter leg. At the same instance, the voltage node V
