IRS26302DJ
V S1 is below the DC+ voltage by the voltage drops associated with the power switch and the parasitic elements of the
circuit. When the high-side power switch turns off, the load current momentarily flows in the low-side freewheeling
diode due to the inductive load connected to V S1 (the load is not shown in these figures). This current flows from the
DC- bus (which is connected to the COM pin of the HVIC) to the load and a negative voltage between V S1 and the
DC- Bus is induced (i.e., the COM pin of the HVIC is at a higher potential than the V S pin).

Figure 33: V S positive
Figure 34: V S negative
In a typical motor drive system, dV/dt is typically designed to be in the range of 3-5 V/ns. The negative V S transient
voltage can exceed this range during some events such as short circuit and over-current shutdown, when di/dt is
greater than in normal operation.
International Rectifier’s HVICs have been designed for the robustness required in many of today’s demanding
applications. The IRS26302DJ has been seen to withstand large negative V S transient conditions on the order of -50
V for a period of 50 ns. An illustration of the IRS26302DJ’s performance can be seen in Figure 35. This experiment
was conducted using various loads to create this condition; the curve shown in this figure illustrates the successful
operation of the IRS26302DJ under these stressful conditions. In case of -V S transients greater then -20 V for a
period of time greater than 100 ns; the HVIC is designed to hold the high-side outputs in the off state for 4.5 μs in
order to ensure that the high- and low-side power switches are not on at the same time.

Even though the IRS26302DJ has been shown able to handle these large negative V S transient conditions, it is highly
recommended that the circuit designer always limit the negative V S transients as much as possible by careful PCB
layout and component use.
