Details

This is a breakout board for ON Semiconductor’s AMIS-30543 microstepping bipolar stepper motor driver, which features SPI-adjustable current limiting, 11 step modes (from full-step through 1/128-step), back-EMF feedback that can be used for stall detection or optional closed-loop control, and over-current and over-temperature protection. The board operates from 6 V to 30 V and can deliver up to approximately 1.8 A per phase without a heat sink or forced air flow (it is rated for 3 A per coil with sufficient additional cooling).

This product is a carrier board or breakout board for ON Semiconductor’s AMIS-30543 Micro-Stepping Motor Driver; we therefore recommend careful reading of the AMIS-30543 datasheet (495k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 3 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the board’s key features:

  • Standard step and direction control interface
  • SPI interface for configuring settings (e.g. step mode, current limit, sleep) and reading status registers
  • Speed and load angle output that can be used for stall detection or closed-loop control of the torque and speed based on the load angle
  • Eleven different step modes: full-step (uncompensated, compensated 1-phase, or compensated 2-phase), half-step (uncompensated or compensated), 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, and 1/128-step
  • SPI-programmable current control (from 132 mA to 3 A) enables your microcontroller to adjust the peak-current limit on the fly as more or less torque or speed is needed
  • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  • Low-EMI PWM with SPI-selectable voltage slopes
  • Compatible with 5 V and 3.3 V microcontrollers
  • Integrated 5V regulator that can be used to supply an external microcontroller
  • Integrated watchdog function
  • Open coil detection
  • Thermal warning indicates when the driver is close to the thermal shutdown temperature
  • Over-current status and shutdown (short-to-ground and shorted-load protection)
  • Reverse voltage protection

Note: This driver needs to be enabled and configured through its SPI interface on power up, so your microcontroller must be capable of acting as an SPI master (either with an SPI peripheral or software SPI).

This product ships with all surface-mount components—including the AMIS-30543 driver IC—installed as shown in the product picture. However, soldering is required for assembly of the included through-hole parts. The following through-hole parts are included:

  • One 1×20-pin breakaway 0.1″ male header
  • Three 2-pin, 3.5 mm terminal blocks (for board power and motor outputs)
  • One 0.1″ shorting block (for connecting IOREF to neighboring VDD pin)

The 0.1″ male header can be broken or cut into smaller pieces as desired and soldered into the smaller through-holes. These headers are compatible with solderless breadboards, 0.1″ female connectors, and our premiumand pre-crimped jumper wires. The terminal blocks can be soldered into the larger holes to allow for convenient temporary connections of unterminated power and stepper motor wires. You can also solder your motor leads and other connections directly to the board for the most compact installation.

PINDescription
VMOT Reverse-protected 6 V to 30 V board power supply connection. Note: Available VDD current is reduced for input voltages under 8 V, and sleep mode is not available for input voltages under 9 V.
VBB This pin gives access to the motor power supply after the reverse-voltage protection MOSFET (see the board schematic below). It can be used to supply reverse-protected power to other components in the system. It is generally intended as an output, but it can also be used to supply board power.
GND Ground connection points for the motor power supply and control ground reference. The control source and the motor driver must share a common ground.
MOTXP Motor output: “positive” end of phase X coil.
MOTXN Motor output: “negative” end of phase X coil.
MOTYP Motor output: “positive” end of phase Y coil.
MOTYN Motor output: “negative” end of phase Y coil.
VDD (5V OUT) The board is powered by an internal 5V regulator, and this pin gives access to the regulated 5 V output. This can be used to supply the neighboring IOREF pin when using this board in 5V systems, and it can be used to power an external microcontroller. When VMOT is over 8 V, approximately 30 mA is available for external components; when VMOT is less than 8 V, the available current drops to less than 10 mA.
IOREF All of the board signal outputs (except SLA) are open-drain outputs that are pulled up to IOREF, so this pin should be supplied with the logic voltage of the controlling system (e.g. 3.3V for use in 3.3V systems). For convenience, it can be connected to the neighboring VDD pin when it is being used in a 5V system.
NXT Changes on this input move the motor current one step up or down in the translator table (even when the motor is disabled). The edge that triggers the step depends on the NXT-polarity configuration bit, which can be changed through the SPI interface (rising edge by default).
DIR Input that determines the direction of rotation. The direction can also be controlled through the SPI interface.
DO SPI data output. (This pin is also often referred to as “MISO”.)
DI SPI data input. (This pin is also often referred to as “MOSI”.)
CLK SPI clock input.
CS SPI chip select input. Logic transitions on this pin are required for SPI communication, even if this is the only device on the SPI bus.
CLR Chip reset input. A logic high on this input clears all internal registers, except in sleep mode.
ERR Error output. This pin drives low to indicate that an error condition has occurred. The specific error can be determined by using the SPI interface to check the error flags.
POR/WD Power-on reset/watch dog function output. This pin provides an active-low signal that can be used as a reset input for an external microcontroller.
SLA (filtered) SLA (speed and load angle) output after a low-pass filter. The result is an analog voltage between 0  V and 5 V that indicates the level of the back-EMF voltage of the motor. This signal can be used for stall detection or closed-loop control of the torque and speed based on the load angle. Note: Since the output of this pin ranges from 0 V to 5 V regardless of IOREF, extra precautions should be taken when connecting this pin to a 3.3V device (such as passing it through an appropriate voltage divider).
