built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature simple two-pin speed direction interface Under-voltage lockout and protection against over-current and over-temperature Simple interface requires only two I/O lines (one for direction and another for speed)
Built-in regulator (no external logic voltage supply needed) Short-to-ground, short-to-supply, and shorted-load protection 4-layer, 2?oz copper PCB for improved heat dissipation Exposed solderable ground pad below the driver IC on the bottom of the PCB Simple step and direction control interface
Reverse-voltage protection on the motor supply H-bridge motor driver: can drive one DC motor Motor supply voltage: 0?V to 11?V Logic supply voltage: 1.8?V to 7?V easy to use with standard solderless breadboards
Reverse-voltage protection Short circuit protection Current sensing and current limiting functionality Inputs compatible with 1.8?V, 3.3?V, and 5?V logic
Inputs compatible with 1.8?V, 3.3?V, and 5?V logic Under-voltage lockout, over-current protection, short circuit protection, and reverse-voltage protection (up to 40?V) High-power: can deliver up to 4?A continuous per phase without extra cooling (6?A max with sufficient additional cooling) Highly configurable through SPI interface Optional STEP/DIR control pins (stepping can also be controlled through SPI interface alone)
No separate logic supply needed; inputs are 3V- and 5V-compatible Under-voltage lockout and protection against over-current/short-circuit and over-temperature Carrier board adds reverse-voltage protection Compact size (0.6??×0.5??)
Built-in regulator (no external logic voltage supply needed) Can interface directly with 3.3?V and 5?V systems Over-temperature thermal shutdown, over-current shutdown, short circuit protection, and under-voltage lockout 4-layer, 2?oz copper PCB for improved heat dissipation
Built-in regulator (no external logic voltage supply needed) Can interface directly with 3.3 V and 5 V systems Under-voltage lockout and protection against over-current/short-circuit and over-temperature Open-load detection Active-low error outputs indicate over-current, over-temperature, or open-load condition Compact size (0.6???×?0.8??) 4-layer, 2 oz copper PCB for improved heat dissipation
