Beschreibung von DRV8829
The DRV8829 is a brushed-DC motor or 1/2 bipolar stepper driver for industrial applications. The device ouptut 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.
