Integrated motion controller with SPI interface. APPLICATIONS CCTV, Security Antenna Positioning Heliostat Controller Battery powered applications Office Automation ATM, Cash recycler, POS Lab Automation Liquid Handling Medical Printer and Scanner Pumps and Valves FEATURES AND BENEFITS DESCRIPTION Two 2-phase stepper motors The TMC5062 is a high performance motion controller and driver for up to two stepper Drive Capability up to 2 x 1.1A coil current motors. It combines two flexible ramp Motion Controller with sixPointramp motion controllers with energy efficient Voltage Range 4.75 20V DC stepper motor drivers. The drivers support SPI & Single Wire UART two-phase stepper motors and offer an Dual ABN Encoder Interface industry-leading feature set, including high- 2x Ref.-Switch input per axis resolution microstepping, sensorless mechanical load measurement, load-adaptive Highest Resolution 256 microsteps per full step velocity and power optimization, and low- Full Protection & Diagnostics resonance chopper operation. Standard SPI dcStep load dependent speed control no step loss interface and an optional UART based single stallGuard2 high precision sensorless motor load detection wire interface simplify communication. coolStep load dependent current saves up to 75% energy Integrated protection and diagnostic features spreadCycle high-precision chopper for best current sine wave support robust and reliable operation. High form and zero crossing with additional chopSync2 integration, high energy efficiency and small Compact Size 7x7mm QFN48 package form factor enable miniaturized designs with low external component count for cost- effective and highly competitive solutions.

It offers a versatility that covers a wide spectrum of applications from battery systems up to embedded applications with 1.1A RMS motor current per coil. The small form factor keeps costs down and allows for miniaturized layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. High energy efficiency and reliability from TRINAMICs coolStep and dcStep technologies deliver cost savings in related systems such as power supplies and cooling. EXAMPLE DESIGN WITH ONE STEPPER MOTOR Ref. Switches The stepper motor driver outputs are switched in SPI parallel. A dual ABN encoder High-Level M CPU TMC5062 Interface interface and two reference switch inputs are used. Encoder An application with two COMPACT DESIGN FOR TWO STEPPER MOTORS stepper motors is shown. Additionally the ABN Motor 1 encoder interface and two reference switches can be M UART used for each motor. A High-Level CPU TMC5062 Interface single CPU controls the M whole system. The CPU- board and controller / driver Motor 2 boards are highly economical and space saving. A UART interface can be used as an option to SPI for pin count limited controller or remote drives. TMC5062-EVAL EVALUATION BOARD EVALUATION & DEVELOPMENT PLATFORM The TMC5062-EVAL is part of TRINAMICs universal evaluation board system which provides a convenient handling of the hardware as well as a user-friendly software tool for evaluation. The TMC5062 evaluation board system consists of three parts: STARTRAMPE (base board), ESELSBRCKE (connector board including several test points), and TMC5062-EVAL.
