New Release Texas Instruments Stepping Motor Driver "DRV8461"
Until now, stepping motors have been used in a variety of applications, taking advantage of their ability to accurately control positions.
Texas Instruments (hereafter, TI) has a lineup of stepping motor drivers that meet these challenges.
Among them, this article will introduce a new product, the DRV8461, a stepping motor driver with a peak current of 3A/2.1Arms and a low current rating.
If you are interested in DRV8461, please feel free to contact us below.
Features of the DRV8461
This product has the following four features.
- Supports a wide range of voltages: Achieves an operating voltage range of 4.5 - 65V
- Supports large current: Supports full-scale current 3A (2.1Arms)
- Contributes to loss reduction: Low on-resistance 300mΩ (H+L@24V/25°C)
- Contributes to space saving: inside the current sense circuit

Four new functions installed in new stepping motor driver products
TI's new stepping motor driver products (including this product) are equipped with the following four new products that have never existed before.
- Automatic Microstepping : Microstep automatic interpolation function with a maximum resolution of 256 (improved rotation accuracy and quietness)
- Custom Microstepping: Customizable current profile according to motor torque characteristics (improved rotation accuracy)
- Silent Step Decay Mode: Adopts voltage mode control in the low speed range, enabling ideal sinusoidal current drive (quietness improvement)
- Auto-torque & Standstill Power Saving Mode: Automatically controls current according to dynamic load torque to improve efficiency and reduce IC and motor loss (higher efficiency)
This article also introduces other products with new features.
In addition, please download the materials that explain the principles of the four new functions in detail from the following.
