NSD8381
Overview
The NSD8381 is a bipolar stepper motor driver, supporting up to max 1.35A full-scale current, for wide range automotive applications including headlight position, projector adjustment actuator in HUD and other valves or BDC motors used in thermal management application.
The device includes current chopping regulation, internal up to 1/32 micro-step translator and multiple decay modes selection to enable stepper motor smooth motion. Furthermore, configurable full-scale current, external pin as simple STEP / DIR input and HOLD mode, all these functions easy customer management of stepper motor operation.
The device is fully protected from faults and short circuits, including undervoltage, overcurrent and overtemperature. Also, open load diagnosis and stall detection can be individually requested to perform during system running. Both SPI interface and dedicated DOUT1/DOUT2 pins are provided to indicate these fault status & alert to microcontroller.
