ALLEGRO A4983 STEPPER DRIVER


The A interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened. Overview This product is a carrier board or breakout board for Allegro’s A DMOS Microstepping Driver with Translator; we therefore recommend careful reading of the A datasheet k pdf before using this product. To achieve high step rates, the motor supply is typically much higher than would be permissible without active current limiting. PayPal Carta di credito Bonifico bancario anticipato.

This product can get hot enough to burn you long before the chip overheats. To achieve high step rates, the motor supply is typically much higher than would be permissible without active current limiting.

Connecting or disconnecting a stepper etepper while the driver is powered can destroy the driver. We’ll notify you when there are updates to this product. There are no news items available for this product. Take care when handling this product and other components connected to it.

A4983: DMOS Microstepping Driver with Translator

A microstepping driver such as the A allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. Please see allgero Pololu stepper driver board for a newer stepperr e. Please note that the current limit is dependent on the Vdd voltage. More generally, rewiring anything while it is powered is asking for trouble. We also sell a smaller version of the A carrier without voltage regulators.

Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. Otherwise, the intermediate current levels will not be correctly maintained, and the motor will effectively operate in a full-step mode.

Allegro MicroSystems – A DMOS Microstepping Driver with Translator

Like nearly all our other carrier boards, this product ships with all surface-mount components—including the A driver IC—installed as shown in the product picture. Otherwise, the intermediate current levels will not be correctly maintained, and the motor will effectively operate in a full-step mode.

Please note that measuring the current draw at the power supply does not necessarily provide an accurate measure of the coil current. Step and microstep size Stepper motors typically have a step size specification e. See the A datasheet for more information. Print Email a friend Feeds. Feedback Comments or questions? You can also solder your motor leads and other connections directly to the board.

Simply inputting one pulse on the STEP input drives the motor one microstep. A microstepping driver such allegto the A allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. The headers can be soldered in for use with solderless breadboards or 0.

Most people buy it already soldered to a breakout board, which makes it act like a single aloegro DIP chip that handles things that required 2 or 3 chips and a fistful of discrete components in earlier times.

Stepper motors typically have a step size specification e. Like nearly all our other carrier boards, this product ships with all surface-mount components—including the A driver IC—installed as shown in the product picture. Current limiting To achieve high step rates, the motor supply q4983 typically much higher than would be permissible without active current limiting.

Also, if the supply voltage is very high compared to what the motor needs to achieve the set current, the duty cycle will be very low, which also leads to significant differences between average and RMS currents.
