Description
General part information
DRV8461 Series
The DRV8461 is a wide-voltage, high-power, high-performance stepper motor driver. The device supports up to 65-V supply voltage, and integrated MOSFETs with 300 mΩ HS + LS on-resistance allow up to 3-A current.
The auto-torque feature boosts efficiency by adjusting the coil current according to load torque. Standstill power saving mode reduces power loss during motor holding condition. Silent step decay mode delivers noiseless operation at low speeds and standstill. The internal current sense eliminates the need for sense resistors, saving PCB area and system cost. Built-in indexer supports up to 1/256 microstepping, and the automatic microstepping mode interpolates the input STEP signal to reduce overhead on the controller. Sensorless stall detection eliminates end stops from the system. The device supports other protection and diagnostic features for robust and reliable operation.
The DRV8461 requires minimal tuning to configure the advanced features. The DRV8461 supports higher power density compared to external FET drivers, with a smaller PCB area. High energy efficiency with precise, noiseless operation makes the DRV8461 an ideal choice for high-performance stepper systems.
