TMC5240AUU+

Motor Drivers, Controllers Overview

The TMC5240AUU+ is a smart integrated stepper motor controller and driver IC from Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 36V DC. The device features fully integrated H-bridges with a maximum output current of 5.0A per bridge, limited by overcurrent protection. At room temperature, the maximum RMS current rating is 2.1A per H-bridge. The unit supports up to 256 microsteps per full step and includes an embedded indexer. Communication interfaces include SPI and single-wire UART.

• Features SpreadCycle chopper for high dynamic torque control.
• Includes non-dissipative integrated current sensing (ICS) to eliminate external power resistors.
• Provides comprehensive diagnostic capabilities including thermal shutdown and overcurrent protection.

Motor Drivers, Controllers Applications

• 3D printers
• CCTV and security systems
• HVAC pump and valve control
• Office automation and paper handling

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix 'UU' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status directly with authorized distributors as supply constraints may apply. Validate that the operating temperature range aligns with your system design parameters before finalizing procurement.

Motor Drivers, Controllers Selection Notes

Select this component when designing systems requiring silent stepper motor operation combined with precise motion control. The integrated indexer reduces host processor load. Consider the thermal performance limits based on PCB layout and ambient conditions, as the 2.1A RMS rating is temperature-dependent. Ensure the host controller supports the required SPI or UART interface protocols for configuration and monitoring.
