Part Number: DRV8824 Other Parts Discussed in Thread: DRV8849 , DRV8425 , DRV8436 , DRV8434 , DRV8424 Tool/software: We are using DRV8824 for our product. But while planning for new design and existing part correction, we found that, part is in LTB. Suggest…
Hi Peter,
The DRV8912-Q1 does have an Overcurrent Protection circuit (OCP) that will protect the device from inrush, shorts, or transient current spikes that may damage the device.
If Current Regulation is needed, than yes I would agree that the DRV8845…
Hi Henry,
The DRV201A would be a good solution for lens control of IP camera. We typically see both brushed and stepper motor drivers often used as well for IP camera design.

Hey Dane,
Unfortunately we don't appear to have any drivers with SPI that can control 2x stepper motors. Here's a page with our stepper drivers with 4 full bridges (can control 2 steppers) - https://www.ti.com/motor-drivers/stepper-driver/products…
Hey Given,
We do not have a P2P solution for this device. The closest we have is DRV8849 which can control 2x stepper motor but no zoom/focus motor.
Regards,
Jacob
Lawrence,
Schematic looks OK, but this is a relatively old device. For new designs, we have the DRV8849 that has integrated micro-stepping and integrated current sensing (removes large power resistors in the GND path).
Package is also much smaller in…
Hey Dane,
This sounds like it would be a very specialized chip, we don't have any devices that support hall sensors. You'd have to interface with the magnetic Hall sensor with an external microcontroller.
We only have a few stepper motor drivers…
Hey Derek,
The DRV8462 would certainly work for this application. You are correct that you would need 1 part per stepper motor, as it is only a single stepper motor driver. This is one of our most feature-packed stepper motor drivers, so it might be overkill…
Part Number: DRV8849EVM Hello
I'm testing the DRV8849EVM to drive 2 stepper motors at full scale current 1.5A, provoking an fault on driver, not present if I use less current.
Afther mesuring temperature on chip, its over 100º before failing, I assume…
