The AWINIC AW8646QNR is a flexible microstepping stepper motor driver designed for bipolar stepper motors. It supports step modes up to 1/32th, making it suitable for applications requiring precise motor control.
The device operates within a 3V to 12V supply voltage range and can deliver 1.4A full-scale current or 1A RMS current per H-bridge. It features a low typical Rdson of 0.8Ω and supports 1.8V logic levels. The AW8646QNR includes programmable off-time options (10, 20, or 30µs) and supports various decay modes, including Adaptive Decay, Mixed Decay, Slow Decay, and Fast Decay.
Integrated protection features include Short-Circuit Protection, Over-Temperature Protection, and Under-Voltage Protection (UVLO). Fault conditions are indicated via an nFAULT pin. The driver is available in a compact QFN 4mm x 4mm x 0.85mm-24L package, suitable for space-constrained designs.
Applications for the AW8646QNR include mobile phones, tablets, printers, and video security cameras, where precise and efficient stepper motor control is required.
