I have the following request from a customer:
Can TI give an example circuit that meets ISO13849 PLd Category 3 using Hercules and Safety PMIC (TPS65381Q1)?
This customer is planning to use the TMS570LC4357.
Let me know if more information is needed.
Hi Nicholas,
It is a big topic. We can use the same concept in "TF85875T_release_2014_06_18.pdf". This concept (single lockstep MCU + safety PMIC) was designed for STO (safe torque off) to achiev Pld CAT3. It was assessed with TUV SUD and approved.
