Part Number:DRV8832
Hello,
i am new to motor control circuit and i am looking for a low voltage motor driver for a power constraint battery operated application. I looked at the selector guide at slyb165i.pdf but i am not sure how to pick one as per the requirements below. Some pointers here will help me a lot
Here are the requirements.
- Control either a DC brushed motor (rated 4-5V) or a Servo motor SG90 (rated 5v) Only one at a time on the output connector
- Require precision shaft position control
- It will be powered by two CR2032 batteries
- There is a SoC that is capable of PWM or PH/EN control
- When motor not in use still the battery would be connected and hence shouldnt draw any power (ideally)
- When motor shaft position stalls due to physical lock conditions, the controller should generate an interrupt to SoC/CPU (3.3v level).
DRV8832 seems to come near my requirement but without motor shaft lock position
Pl suggest if Servo or DC motor can be controlled from the same DRV device/circuit (either one present at a time)
How to detect motor stall from SoC/CPU
How to keep shaft position in desired angle at varying battery levels?
Thank you in advance
