3 Description

The DRV8805 provides an integrated solution for

driving unipolar stepper motors. It includes four lowside

drivers with overcurrent protection and provides

built-in diodes to clamp turnoff 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).

In the SOIC (DW) package, the DRV8805 can supply

up to 1.5-A (one channel on) or 800-mA (all channels

on) continuous output current per channel, at 25°C. In

the HTSSOP (PWP) package, it can supply up to 2-A

(one channel on) or 1-A (four channels on)

continuous output current per channel, at 25°C with

proper PCB heatsinking.

Internal shutdown functions are provided for

overcurrent 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 thermallyenhanced

SOIC package and a 16-pin HTSSOP

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