DRV8850: Consideration of using VM=2V

Part Number:DRV8850

Hi

For brushed DC motor opeartion, use of VM=2V is required.

Motor specification is following.

VM=2V

Istart=2A

Ilock=4A

In addition, motor lock detection function should be implemented in system.

DRV8850 has VPROPI, so current sense output can feed-back to MCU (ADC) and MCU can shut off the driver with specific current.

However, there is concern of using DRV8850 with VM= 2v because of UVLO.

Do you give us advice to use DRV8850 with VM=2V?

Or can you provide other solution for this requirement?

BestRegards
