Hi,
Good day.
In the datasheet it states, "The DRV8770 can drive an H-bridge with power supply up to 100 V." Does that mean the load or motor can see 100Vp-p or 200Vp-p?
Thank you for your response.
Regards,
Cedrick

What is the maximum Low-side drain pin voltage? If I put the load between MOTA and MOTB then switch directions wouldn't the load see 100V and -100V when the supply is 100V?
Thank you for your response.

Hi Cedrick,

This means the H-bridge power supply can be up to 100V. So the SHx pins can support up to 100V as well. The voltage across the load (SHx pins) is +-100V.
What is the maximum Low-side drain pin voltage? If I put the load between MOTA and MOTB then switch directions wouldn't the load see 100V and -100V when the supply is 100V?
The max low-side drain pin as I mentioned above is 100V. The difference between MOTA and MOTB will always be either 0V or 100V ideally when PVDD=100V.
