The TPS7H4001-SP WCA model is a behavioral model intended for simulation of frequency response characteristics, such as phase margin, phase margin crossover frequency, and gain margin. Monte Carlo analysis can also be performed to observe the distribution of behavior across a specified sample size of devices. The following sources of variation are incorporated into the model:
Represented by data taken at 25°C before and after 1,000 hours of testing at 125°C, and meant to emulate 15 years operating at 65-95°C as defined by Group C specifications in MIL-PRF-38535
In the model, the specific device parameters influenced by the above variation include:
