STMicroelectronics has introduced a family of monolithic motor drivers that form the heart of an open, scalable solution for a wide range of motion control applications. ST's new powerSPIN platform includes devices suitable for driving DC motors, stepper motors and brushless DC motors. The powerSPIN devices are built with ST's BCDIII process which combines bipolar, CMOS and isolated DMOS structures on the same chip. This allows all of the control and power circuitry required to drive the motor to be integrated in a single chip.
The range of smart motor drivers includes the L6205 and L6225, L6206 and L6226, L6207 and L6227, L6208 and L6228 dual DC or bipolar stepper motors and the L6235 and L6229 for brushless DC motors.
For example, the L6208 integrates all the circuitry required to drive a two-phase stepper motor, including a dual DMOS full bridge, the constant off-time PWM current controller that performs the chopping regulation, and the phase sequence generator that generates the stepping sequence. Similarly, for driving three-phase brushless DC motors, the L6235 integrates a three-phase DMOS bridge, a constant off-time PWM current controller and the decoding logic for single-ended Hall sensors that generates the required sequence for the power stage. Both devices feature non-dissipative over-current protection on the high side Power MOSFETs and thermal shutdown.
Two classes of pin-to-pin compatible powerSPIN devices with different current ratings are offered: the L620x devices and the L6235 are rated at 5,6 A peak current (2,8 A rms), while the L622x devices are rated at 2,8 A peak, (1,4 A rms).
The powerSPIN platform is designed to allow optimal matching between the selected device and the application requirements, eliminating the need for expensive over-specification. The devices are supported by an evaluation environment, called practiSPIN, which comprises boards and a software tool that provides an interface between a PC and the motor driver, as well as performing power dissipation and thermal analysis simulation.
