DRV8428: M0/M1 connection for "0"

Part Number: DRV8428

Hi team,

Could you give me comment on following customer questions?

Q1. When the customer wants to set M0/M1 pin as "0", can M0/M1 pin be directly shortened to GND? 

Q2. If not on the answer for Q1, and if some pull down resistor should be needed, what value of pull down resistor should be good, such as 10kOhm or 100kOhm?

Best regards,

Takeshi Sasaki

    Sasaki-san,

    Q1. When the customer wants to set M0/M1 pin as "0", can M0/M1 pin be directly shortened to GND? 

    Yes. 

    Q2. If not on the answer for Q1, and if some pull down resistor should be needed, what value of pull down resistor should be good, such as 10kOhm or 100kOhm?

    To get flexible M0/M1 setting, I would recommend external resistors and pick 10kohm as pull-down resistor.
