SBAS920 October 2018 AMC1302-Q1
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 54 shows the typical full-scale step response of the AMC1302-Q1. Consider the delay of the required window comparator and the MCU to calculate the overall response time of the system.
The high linearity and low temperature drift of the offset and gain errors of the AMC1302-Q1 (see the Typical Characteristics section) allows design of motor drives with low torque ripple.
