Other Parts Discussed in Thread: DRV8307

Can anyone help me in connection for BLDC motor contains single ended Hall sensor (Portescape motor part number - C-161003-45B ) to DRV8307 BLDC motor driver. In datasheet given as differential HALL sensor output given to Differential Comparator of DRV8307 Driver, how can i connect single ended HAL sensor.

Thanks in advance..

Hi Ardash,

The minimum speed is motor dependent. As the duty cycle is decreased, the motor will slow down.

Thanks a lot,, i going to get the BLDC motor from port-escape today, i doubt following doubt.

1. how is the conversion rate of PWM input to 3 pole logic PWM with 12bit PWM generator

2. fHall range is 0 - 30kHz is that is that UVW hall sensor out frequency, if it is then Hallout signal range is also same.

Regards
