NCV70522DQ
Micro-Stepping Motor Driver
Introduction
The NCV70522DQ is a micro−stepping stepper motor driver for
bipolar stepper motors. The chip is connected through I/O pins and a
SPI interface with an external microcontroller. The NCV70522DQ
features an internal current−translation table: it takes the next
micro−step depending on the clock signal on the stepping input pin
(NXT) and the status of the direction register or input pin (DIR). A
reliable current control is achieved using an integrated proprietary
PWM algorithm.
The NCV70522DQ includes a so−called “Speed and Load Angle”
(SLA) output, allowing the creation of stall detection algorithms and
control loops to adjust torque and speed based on the motor’s back
electromotive force (BEMF).
The NCV70522DQ is implemented in I2T100 technology, enabling
both high voltage analog circuitry and digital functionality on the
same chip. The device is fully compatible with automotive voltage and
temperature requirements and suited to general purpose stepper motor
applications in the automotive, industrial, medical and marine
domains.
