DESCRIPTION
The DRV8829 provides an integrated motor driver solution for DC and stepper motors used in cash handling
machines 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 single full H-bridge to drive the motor winding. The DRV8829 can supply up to 5-A
peak or 3.5-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 DRV8829 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
