3 Description
The DRV8813 provides an integrated motor driver
solution for printers, scanners, and other automated
equipment applications. The device has two H-bridge
drivers, and can drive a bipolar stepper motor or two
DC motors. The output driver block for each consists
of N-channel power MOSFETs configured as full H-
bridges to drive the motor windings. The DRV8813
can supply up to 2.5-A peak or 1.75-A RMS output
current (with proper heatsinking at 24 V and 25°C).
A simple parallel digital control interface is compatible
with industry-standard devices. Decay mode is
programmable.
Internal shutdown functions are provided for
overcurrent protection, short circuit protection,
undervoltage lockout and overtemperature.
The DRV8813 is available in a 28-pin HTSSOP
package with PowerPAD™ (Eco-friendly: RoHS & no
Sb/Br).
