DESCRIPTION

The DRV8805 provides an integrated solution for driving unipolar stepper motors. It includes four low side drivers

with overcurrent protection and provides built-in diodes to clamp turn-off transients generated by the motor

windings.

Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated. Three

stepping modes are supported: 2 phase (full-step), 1-2 phase (half-step), and 1-phase (wave drive).

The DRV8805 can supply up to 1.5-A (single channel on) or 800-mA (four channels on) continuous output

current (with adequate PCB heatsinking at 25°C).

Internal shutdown functions are provided for over current protection, short circuit protection, under voltage

lockout and overtemperature and faults are indicated by a fault output pin.

The DRV8805 is available in a 20-pin thermally-enhanced SOIC package and a 16-pin HTSSOP package

(Eco-friendly: RoHS & no Sb/Br).
