9.2.1.3 Application Curves
In traction inverter applications, the power switches must be protected in case of an overcurrent condition. To
allow for fast powering off of the system, a low delay caused by the isolated amplifier is required. Figure 50
shows the typical full-scale step response of the AMC1301-Q1 device. Consider the delay of the required window
comparator and the MCU to calculate the overall response time of the system.

Figure 50. Step Response of the AMC1301-Q1 Device
The high linearity and low temperature drift of offset and gain errors of the AMC1301-Q1 device, as shown in
Figure 51, allows design of motor drives with low torque ripple.
