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.
