The A4982SLPTR-T is a microstepping motor driver designed for bipolar stepper motors, capable of operating in full-, half-, quarter-, and sixteenth-step modes. It supports an output drive capacity of up to 35 V and ±2 A. The driver features a built-in translator for simplified operation, allowing for easy control with a single pulse on the STEP input, eliminating the need for complex programming or phase sequence tables. This device includes a fixed off-time current regulator that can operate in Slow or Mixed decay modes, which helps reduce audible motor noise and improve step accuracy. It also incorporates internal protection features such as thermal shutdown, undervoltage lockout (UVLO), and crossover-current protection. The A4982SLPTR-T is available in a 24-pin TSSOP package with an exposed thermal pad for enhanced thermal dissipation and is compliant with no smoke no fire (NSNF) design standards. Engineers may find this product suitable for applications where a straightforward interface is required, and where space and thermal management are critical considerations.
The A4982 simplifies microstepping motor control with its integrated translator, automatic current decay mode selection, and integrated protection features.
