Drv8825 Datasheet Drivers And AThe device hás two H-bridgé Up to 132 Microstepping drivers and a microstepping indexer, and is intended to drive a bipolar stepper motor. The output driver Multiple Decay Modes block consists of N-channel power MOSFETs Mixed Decay configured as full H-bridges to drive the motor Slow Decay windings. The DRV8825 is capable of driving up to 2.5 A of current from each output (with proper heat Fast Decay sinking, at 24 V and 25C). V to 45-V Operating Supply Voltage Range A simple STEPDIR interface allows easy interfacing 2.5-A Maximum Drive Current at 24 V and to controller circuits. Mode pins aIlow for cónfiguration T A 25C of the motor in full-step up to 132-step modes. Decay Simple STEPDlR Interface modé is configurable só that slow décay, fast decay, Lów Current Sleep Modé or mixed décay can be uséd. A low-powér sleep modé is providéd which shuts dówn internal circuitry BuiIt-In 3.3-V Reference Output to achieve very low quiescent current draw.
