The average switch threshold of each channel is trimmed at wafer test under the
following operating conditions:
average current command = 299
hysteresis = 80 mVpp.
The TLE 7241E includes 5 error correction registers for each channel. The registers are
written during room temperature wafer testing. After the device has been trimmed, the
average of the upper and lower switch thresholds is measured at 5 average current
operating points. The difference in the measured value and the ideal value is
permanently stored in the 5 error registers. The contents of the error correction register
are an 8 bit signed value that must be added to the ideal current command to minimize
the average current error.
