3 Description
The DRV8462 is a wide-voltage, high-power, highperformance
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 5-A current with the DDW package; and up to
10-A current with the DDV package.
The auto-torque feature boosts system efficiency by
adjusting the coil current according to load torque.
The standstill power saving mode reduces power
loss during motor holding condition. The silent step
decay mode guarantees noiseless operation. The
internal current sense architecture eliminates the
need for external sense resistors, therefore saving
PCB area and system cost. The built-in indexer of
the DRV8462 supports up to 1/256 microstepping,
and the automatic microstepping mode interpolates
the input STEP signal to reduce overhead on the
controller MCU. 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 only minimal tuning to
configure the advanced features. High energy
efficiency coupled with precise, noiseless operation
makes the DRV8462 an ideal choice for highperformance
stepper motor systems.
