Descrizione

Traduzione AI

The DRV8824 provides an integrated motor driver solution for printers, scanners, and other automated equipment applications. This device features two H-bridge drivers and a microstepping indexer, and is specifically designed to drive a bipolar stepper motor. The output driver block contains N-channel power MOSFETs configured as full H-bridges to drive the motor windings. The DRV8824 can drive up to 1.6A of current from each output (at 24V and 25°C with proper heat dissipation). A simple step/direction interface easily connects to the controller circuit. Mode pins enable motor configuration from full-step to 1/32-step modes. The decay mode can be configured to use slow decay, fast decay, or mixed decay. A low-power sleep mode shuts down part of the internal circuitry, enabling extremely low quiescent current and power consumption. This sleep mode can be set via the dedicated nSLEEP pin. Internal shutdown functions are provided for overcurrent, short-circuit, undervoltage lockout, and overtemperature. Fault conditions are indicated via the nFAULT pin.
