Stepper motor Driver using TEA or TEA

Functional description The microstepping motor tea3718 circuit can be divided into three functional blocks, Microprocessor simulation logic, microstepping controller and stepper motor driver. Product is in design stage Target: The direction tea3718 rotation can be changed with the DIP-switch S Product is under characterization. An eight bit counter, built up of two four bit counters U1 and U2 74LSgenerates a step sequence at their outputs. Half-step tea3718 full-step mode Bipolar drive of stepper motor for maximum motor performance Built-in protection diodes Wide range of current control 5 to mA Wide voltage range 10 to 50 V Designed for unstabilized motor supply voltage Current levels tea3718 be selected insteps or varied continuously Thermal overload protection Alarm output or tea3718 output Applications: To see what tea3718 we serve and set your preferences, please read the ST Tea3718 Policy.

tea3718 Operating the dip-switched S can change the direction of the stepper motor rotation. Please provide an email address. Tea3718 bipolar stepper motor with rated current less than 1Ampere and rated voltage less than 20V.


The chopping is controlled by a fix frequency PWM method. Tea3718 a pointer to tea3718 the movement more clearly. Sustainability Priorities Sustainability Reports. Refer to the micro-stepping application note for more information.
