TMC4361-LA-T

Motor Drivers, Controllers Overview

The TMC4361A-LA-T is a stepper motor servo controller IC manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a CMOS technology platform with a supply voltage range of 3 V to 5.2 V and a quiescent current of 10 uA. The device features an output current capability of 4 mA and supports operation temperatures from -40°C to +125°C. It is housed in a 40-QFN (6x6) package with a bare pad, suitable for surface mount installation. The component utilizes SPI and Step/Direction interfaces for configuration and control.

Motor Drivers, Controllers Procurement Notes

Verify the exact suffix designation when ordering, as the 'LA' variant may have specific availability constraints compared to the 'LA-T' tape and reel version. Confirm that the required package type matches the project's PCB layout requirements. Check current distributor stock levels as supply status can vary. Ensure the design accounts for the specified operating temperature range and humidity sensitivity level during assembly.

Motor Drivers, Controllers Selection Notes

Select this component for applications requiring integrated servo control without external microcontrollers for basic motion tasks. The choice between the tray-packaged LA and tape-reel LA-T depends on manufacturing volume and reflow soldering processes. Consider the 40-QFN footprint for space-constrained designs. Verify compatibility with the target power supply voltage limits and thermal dissipation capabilities for the intended enclosure environment.

Motor Drivers, Controllers Part Context
