3 Description
The DRV8828 provides an integrated motor driver
solution for printers, scanners, and other automated
equipment applications. The device has one H-bridge
driver, and can drive one winding of a bipolar stepper
motor or one DC motor. The output driver block
consists of N-channel power MOSFET’s configured
as a full H-bridge to drive the motor winding. The
DRV8828 is capable of driving up to 3-A of 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 DRV8828 is available in a 28-pin HTSSOP
package with PowerPAD™ (Eco-friendly: RoHS & no
Sb/Br).
