  • RE: DRV8144-Q1: DRV8144-Q1 - Slew rate / Rth JA

    Hi, Thank you for your questions. I recommend to use thermal estimator on TI.com for this activity. It includes worst case assumption including slew rate and Rdson. www.ti.com/.../DRV8145-Q1 Then chose worst case. We do not have SPEC for min/max slew…

  • RE: Power dissipation calculation of H-Bridge

    Hi, Thank you for your feedback. regarding No 1, total duration could be more important than number of pulses. If 15.9A peak sinewave period is less than 180ms, looks OK with Ta=85C. However under Ta=105C condition, looks marginal with DRV8144-Q1. It…
