The A3984SLPTR-T is a DMOS 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, making it suitable for various motor control applications. The driver features a built-in translator that simplifies operation by allowing the motor to be driven with a single pulse on the STEP input, eliminating the need for complex programming or phase sequence tables. This product includes automatic current decay mode detection, offering both Slow and Mixed decay modes to optimize performance and reduce audible noise. It also incorporates internal protection features such as undervoltage lockout (UVLO), thermal shutdown, and crossover-current protection, ensuring reliable operation under varying conditions. The A3984 is packaged in a 24-pin TSSOP with an exposed thermal pad, facilitating efficient heat dissipation. Its operating temperature range is from -20°C to 85°C, with a maximum junction temperature of 150°C. This driver is particularly well-suited for applications where space is limited and a straightforward interface is required.
The A3984 offers precise and efficient microstepping control of bipolar stepper motors, featuring 1/16-step resolution, an integrated translator for simplified control, and synchronous rectification for reduced power dissipation.
