Part Number: DRV8885
Hi Experts,
My customer is interested in DRV8885 because of this device does not require an external resistor for current motor.
Customer will use Full-Step and customer's motor is needed 1.5Arms output current. According to datasheet, Table 2, p14, output current is limited by 71% full scale. (stated by DRV8885 recommended operating conditions.) Does it mean 1.5Arms*0.71%=1.065Arms, correct? If so, why is limitation? Is it thermal limitation?
DRV8880 achieved over 1.5Arms output current but it requires a large external resistors for current monitor. It does not prefer for customer.
Do you have any alternative device?
Your support would be much appreciated.
Best Regards,
Fujiwara
