The AW86426 is a flexible microstepping stepper motor driver. It is designed to operate bipolar stepper motor with up to 1/32th step mode for mobile phones, tablets, ａｎｄ other automated equipment applications. The device can be controlled by simple STEP/DIR interface allowing easy interfacing to controller circuits. The output block of each H-bridge driver consists of N-channel ａｎｄ P-channel power MOSFETS configured as full H-bridges to drive the motor windings.
Pins allow configuration of the motor ｉｎ full-step up to 1/32th step modes. Decay mode is configurable so that adaptive decay, slow decay, fast decay, ａｎｄ mixed decay can be used. A low power ｓｌｅｅｐ mode is provided to achieve very-low quiescent current draw.
AW86426 is capable of driving up to 1.1A (Full Scale) ｏｒ 0.77A (RMS) current per H-Bridge
The device offers a complete set of protection features including UVLO, overcurrent protection, short circuit protection, ａｎｄ over temperature. Fault conditions are indicated via the nFAULT pin.
