This sleep mode can be set using a dedicated nSLEEP pin. A low-power sleep mode is provided which shuts down internal circuitry to achieve very low quiescent current draw. Decay mode is configurable so that slow decay, fast decay, or mixed decay can be used. Mode pins allow for configuration of the motor in full-step up to 1/32-step modes. The DRV8825 is capable of driving up to 2.5 A of current from each output (with proper heat sinking, at 24 V and 25☌).Ī simple STEP/DIR interface allows easy interfacing to controller circuits. The output driver block consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. The device has two H-bridge drivers and a microstepping indexer, and is intended to drive a bipolar stepper motor. The DRV8825 provides an integrated motor driver solution for printers, scanners, and other automated equipment applications. Fault Condition Indication Pin (nFAULT).2.5-A Maximum Drive Current at 24 V and.8.2-V to 45-V Operating Supply Voltage Range.
