Issue: One of our customer purchased Motor driver power MOSFET DRV10866DSCR twice. 105pcs and 40pcs
But all those MOSFET has issue. (I can't believe all of the, are defective.)
Motor will suddenly stop specific number of rotations.
PWM input Frequency: 20kHz
Number of Rotation which make motor stop:1550 rpm (Motor Magnets:16pcs)
PWM Input duty when motor stops=around 68%~70%
Applied Voltage to the circuit=5V
Not connected to motor:3mA
When connected to motor and rotating:37mA(duty=100%)
The customer wants FA.
Can you give some advice?
At End-user
No
Working But stop certain Rotation.
Sensor less Motor
Initial failure (That's what customer think)
