9.3.3.2 Lifetime and Environmental Stability

The same compensation techniques used in the TMCS1100-Q1 to reduce temperature drift also greatly reduce lifetime drift due to aging, stress, and environmental conditions. Typical magnetic sensors suffer from up to 2% to 3% of sensitivity drift due to aging at high operating temperatures. The TMCS1100-Q1 has greatly improved lifetime drift, as defined in the Section 7.9 for total sensitivity error measured after the worst case stress test during a three lot AEC-Q100 qualification. All other stress tests prescribed by an AEC-Q100 qualification caused lower than the specified sensitivity error, and were within the bounds specified within the Section 7.9 table. Figure 9-4 shows the total sensitivity error after the worst-case stress test, a Highly Accelerated Stress Test (HAST) at 130°C and 85% relative humidity (RH), while Figure 9-5 and Figure 9-6 show the sensitivity and offset error drift after a 1000 hour, 125°C high temperature operating life stress test as specified by AEC-Q100. This test mimics typical device lifetime operation, and shows the likely device performance variation due to aging is vastly improved compared to typical magnetic sensors.
