Other Parts Discussed in Thread: DRV8872,
The Input logic low voltage On datasheet page.5 , As shown below:
VOL(max) of the MCU(MC9S12XET256MAG) we used is 0.8V,As shown below:
1. Look on the values in the two datasheets. MCU's VOL(max): 0.8V > VDRV8872's VIL(max): 0.5V,That will be a problem, can you provide the DRV8872 VIL/VIH characteristic curve?
2. Our products are already using DRV8872-Q1. Although there is no problem at present, according to the datasheets, wrong control may occur. Is there any relevant supporting information to prove that will not cause problems?
