    Hello Obinna, While the DRV2700 cannot drive a 3uF load at your required voltage and frequency, you may be able to use a discreet solution to boost the output to achieve this. The second stage would need to make sure the load at the DRV2700 fits within…

    Part Number: DRV2700 Hi Sir, Can we use GPIO with 3.3V to communicate with DRV2700? The voltage rating below shows there is no maximum value is defined so I assume VIH can be up to 3.3V (up to VDD). Need your help to confirm it. Thanks, Ian.
