The DRV8462 is a wide-voltage, high-power, high-performance stepper motor driver. The device supports up to 65-V supply voltage, and integrated MOSFETs with 100 mΩ HS + LS on-resistance allow up to 10-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 guarantees 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 DRV8462 requires minimal tuning to configure the advanced features. It supports higher power density compared to external FET drivers, with a smaller PCB area. High energy efficiency with precise, noiseless operation makes the DRV8462 an ideal choice for high-performance stepper systems.
