About the Stall detect motor driver PCB

Stall detect motor driver is an open source PCB design by anthony-bernaert, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 56 × 54 mm, with 69 components from 24 distinct parts.

Other key parts include the DRV8251ADDAR, AP331AWG-7, LMC555xM and TLV709A01DBVR. By type, the board carries 20 resistors, 16 capacitors, 10 diodes, 7 transistors, 6 test points and 4 ICs.

It belongs with the robotics & motion designs in this gallery.

From the project

DC motor driver with current-based stall detection

The board has two inputs that make the motor spin in either direction. When a stall condition is detected, the motor is disabled until both inputs are released. This prevents the stalled motor from heating up and causing the windings to burn out.

In many situations, this removes the need to install mechanical or optical end-stops.

The circuit is built around a DRV8251A motor driver IC, with a few filters and discrete logic components.
