A4982 Allegro Splitter Overview
The A4982 Allegro Splitter (A4982SLPTR-T TSSOP) is a compact, fully integrated stepper motor driver in a 24-lead TSSOP package with exposed pad. It provides four half-bridge outputs and supports microstepping at resolutions from full-step to 1/16-step, making it ideal for precise control of bipolar stepper motors.
Key Features of A4982 Allegro Splitter
- Fully integrated control and power stages in a single DMOS driver
- Four half-bridge outputs, supporting up to 2 A per coil
- Microstep resolution options: 1, 1/2, 1/4 and 1/16 steps
- Wide supply range: 3 V to 5.5 V logic, 8 V to 35 V motor voltage
- Operating temperature from –20 °C to 150 °C (TJ)
- Space-saving 24-TSSOP (4.40 mm width) with exposed pad for heat dissipation
- Genuine product with fast shipping from Zbotic across India
Applications and Use Cases
- Precision motion control in desktop 3D printers and CNC routers
- Robotic arms and pick-and-place machines requiring accurate positioning
- Pan-tilt camera systems for smooth panning and microstepping control
- Automated lab equipment and medical devices needing fine motor adjustments
- Industrial valve and actuator control in factory automation
How to Use A4982 Allegro Splitter
To use the A4982 Allegro Splitter, solder the device onto your PCB matching the TSSOP footprint with a thermal land for the exposed pad. Connect logic inputs (STEP, DIR, MS1/MS2) to your microcontroller’s GPIO pins, supply 3–5.5 V to VDD and 8–35 V to VMOT, and wire the stepper motor coils to the four half-bridge outputs. Configure microstep resolution via MS1/MS2 pins, add decoupling capacitors to the supply rails, and ensure adequate board-level heat dissipation.

Frequently Asked Questions
Can the A4982 Allegro Splitter handle a 2 A stepper motor?
Yes. The A4982 delivers up to 2 A output current per coil when properly mounted with adequate PCB copper for heat spreading. Use external heat sinks or thermal vias if operating near the upper current limit.
How do I select microstep resolution?
Microstepping is set using the MS1 and MS2 logic pins. By pulling these pins high or low, you can choose full-step, half-step, quarter-step, or sixteenth-step operation as specified in the datasheet.
What PCB layout considerations are needed for the exposed pad?
Include a matching thermal land on the PCB with multiple copper pours and vias under the TSSOP exposed pad to dissipate heat. Apply solder paste in a controlled pattern and use reflow profiling to ensure reliable solder joints.
