Design Considerations

Power windows, doors, mirrors, and seats share common elements in motor control systems. PSoC 3 offers platform development for multiple configurations as well as the ability integrate all intelligent control functionality for up to 4 simultaneous motors per device including:

Pulse Detect

 •  Eliminate Hall-effect sensors
 •  Store position memory for precision control or presetting
 •  Monitor rotation speed

Current Monitoring

 •  Detect rotational resistance
 •  Detect shorts and burnouts

System Communications

 •  Decouple control
 •  Decouple user interface
 •  Decouple monitoring

Motor Control

 •  4 PWMs for 4 simultaneous controls
 •  Reduce complexity of motor drivers
 •  Up to 8 motor multiplexed control

Application Notes

  • AN2197 shows how to use the PSoC® (Programmable System-on-Chip) to drive a low-power stepper motor for smart pointer gauges. This application note demonstrates how to perform micro stepping in the stepper motor using PSoC 1. In addition, this application demonstrates using a PC-based utility to control the pointer position in the stepper motor.

  • This application note introduces the basic concepts of CAN (Controller Area Network) and demonstrates how CAN bus communication is implemented using PSoC® 3 and PSoC 5LP.

  • AN58304 provides an overview of the analog routing matrix in PSoC® 3 and PSoC 5LP.

  • AN58827 discusses how internal trace and switch resistance can affect the performance of a design and how these issues can be avoided by understanding a few basic details about the PSoC® 3 and PSoC 5LP internal analog architecture.

  • The special input/output (SIO) pins provide differential input buffer and a means to regulate the high-level output voltage (VOH). The SIO pins are tolerant to input voltages higher than the I/O supply voltage and can sink up to 25 mA current. This application note explains the following applications of SIO pins: comparator, charge pump, Salen-key filter, level shifter, half wave rectifier, peak detector, and sleep wakeup using SIO comparator.

Development Kits/Boards

  • The CY8CKIT-001 PSoC® Development Kit (DVK) provides a common development platform where you can prototype and evaluate different solutions using any one of the PSoC 1, PSoC 3, PSoC 4, or PSoC 5 architectures.

  • The CY8CKIT-017 CAN/LIN Expansion Board Kit (EBK) is an expansion board that is used with the CY8CKIT-001 PSoC® Development Kit (DVK) or the CY8CKIT-030 PSoC 3 Development Kit (DVK). This EBK enables you to evaluate the Controller Area Network (CAN 2.0A/B) and Local Interconnect Network (LIN 2.1/2.0)slave communication capability of PSoC 3 and PSoC 5 devices in conjunction with Cypress's PSoC Creator™ Integrated Development Environment. The hardware of this EBK includes transceiver circuits for 1 CAN and 2 LIN interfaces. This EBK consists of 2 CAN example projects and 1 LIN example project. You can design your own projects with an easy-to-use CAN and LIN slave components in Cypress's PSoC Creator™ software, or by altering code examples provided with this kit.

  • The CY8CKIT-037 is used for PSoC 4 solution evaluation for motor control application. The kit supports BLDC (BrushLess Direct Current) motors, PMSM (Permanent Magnetic Synchronous Motors) and stepper motors. We provide example projects including single-shunt and sensorless FOC (Field Oriented Control), sensored BLDC control, sensorless BLDC control and stepper motor control example projects.
