Description

The AWD86436CSR 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. A low power sleep mode is provided to achieve very-low quiescent current draw. AWD86436CSR 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.
