Product Details:
The A3980KLP-T, manufactured by Allegro MicroSystems, is a bipolar stepper motor driver integrated circuit designed for operation within a supply voltage range of 3.0V to 5.5V. Fabricated using a mixed-signal BiCMOS process, this device integrates control logic, gate drive circuitry, and output power DMOS transistors to facilitate precise microstepping control of bipolar stepper motors. The A3980KLP-T incorporates a fixed off-time PWM current regulator, enabling current limiting and smooth motor operation. Protection features include overcurrent protection, thermal shutdown, and undervoltage lockout, ensuring robust operation in demanding applications. The device is housed in a 28-lead TSSOP (Thin Shrink Small Outline Package) suitable for surface mount assembly, offering a compact footprint for space-constrained designs. External components are required for current sensing and PWM timing.
