Part Number: DRV8876
Hi
I want to use DRV8876 with following motor.
VM=24V
Iout = 0.34A
Istartup = 0.9A
These parameters are given by the customer. (There is no datasheet)
In DRV8876EVM, Vref is set as 3.3V (Itrip = 2.2A).
And I changed RIMODE to 20Kohm.
I set DRV8876 to ENPH mode and fault is asserted as soon as I start the motor in forward direction and the motor never startup.
This happens whether the DRV8876 is in reverse mode or PWM mode.
I doubt the motor might require the current over 2.2A.
Can you suggest me how to know the correct start up current?
BestRegards
