Other Parts Discussed in Thread: DRV8212, DRV8837
My customer is using DRV8837C for their smart lock end equipment. They have following questions would like to confirm:
The Iocp (min) is 1.2A, and the tDEG is 1us. Following picture is the start-up current. Considering the application scenario like that: Everyday there are maybe 5 times the smart lock will turn on, which further caused the start-up current goes up to around 1.4A with more than 1us deglitch time. Then, DRV8837C will go into OCP status, and the phase current will decrease. Such kind of application scenario will continue maybe 5 years or even longer. Do you think are there any risks for this case? Do you think whether it is reliable if customer used the chipset like that?
