3 Description
The DRV8829 is a brushed-DC motor or 1/2 bipolar
stepper driver for industrial applications. The device
output stage consists of an N-channel power
MOSFET H-bridge driver. The DRV8829 is capable of
driving up to 5-A peak current or 3.5-A rms current
(with proper printed-circuit-board ground plane for
thermal dissipation and at 24 V and TA = 25°C).
The PH/EN pins provide a simple control interface.
An internal sense amplifier allows for adjustable
current control. A low-power sleep mode is provided
for very low quiescent current standby using a
dedicated nSLEEP pin. Current regulation decay
mode can be set to slow, fast, or mixed decay.
Internal protection functions are provided for
undervoltage, overcurrent, short-circuits, and
overtemperature. Fault conditions are indicated by a
nFAULT pin.
