SLOSE84B August 2022 – October 2023 DRV8452
PRODUCTION DATA
The DRV8452 is a wide-voltage, high-power, high-performance stepper motor driver. The device supports up to 55-V supply voltage, and integrated MOSFETs with 100 mΩ HS + LS on-resistance allow up to 5-A current.
The auto-torque feature boosts efficiency by adjusting the current according to load torque. Standstill power saving mode reduces power loss during motor holding condition. Silent step guarantees noiseless operation at low speeds and standstill. Internal current sense eliminates the need for sense resistors, therefore saving PCB area and 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 DRV8452 requires minimal tuning to configure the features. It supports higher power density than external FET drivers, with a smaller PCB area. High energy efficiency coupled with precise, noiseless operation makes the DRV8452 an ideal choice for high-performance stepper systems.
