DRV8872-Q1: Questions: VIL on the DRV8872 Datasheet.

Part Number: DRV8872-Q1
Other Parts Discussed in Thread: DRV8872,

Dear Sirs,

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?


  • Hello,

    Unfortunately, we can't recommend operating the device outside of the datasheet specifications. 

    Have you verified the voltage from your MCU?  Chances are the applied voltage is lower than 0.5V (meeting DRV8872-Q1 spec) especially driving into a high impedance input.
