L6482HTR

Overview

The L6482HTR is a fully integrated microstepping motor controller and driver designed for two-phase bipolar stepper motors. It operates within a supply voltage range of 7.5 V to 85 V and features an SPI interface supporting up to 5-Mbit/s communication. The device integrates a dual full-bridge gate driver for N-channel MOSFETs, embedded non-dissipative overcurrent protection, and advanced current control with auto-adaptive decay mode. It supports programmable motion profiles and achieves up to 1/16 microstepping resolution.

Feature Summary

• Integrates a digital control core for generating user-defined motion profiles including acceleration, deceleration, speed, and target position.
• Features a rich set of protections including thermal, low bus voltage, overcurrent, and motor stall detection.
• Provides advanced current control utilizing an adaptive decay mode to achieve high-resolution microstepping.

Applications

• Driving two-phase bipolar stepper motors with microstepping requirements
• Automated industrial machinery requiring precise motion control
• Applications demanding robust fault protection in motor drive systems

Procurement Notes

Verify the specific suffix 'HTR' indicates tape-and-reel packaging when sourcing components. Confirm that the operating temperature range and package type align with the design requirements. Ensure compatibility with the SPI interface specifications and voltage limits before integration into the final system design.

Selection Notes

Select this component for applications requiring a fully integrated solution for bipolar stepper motors. It is suitable where programmable motion profiles and comprehensive protection features are necessary. Consider the SPI interface speed and voltage range constraints when designing the control circuitry.

Part Context

The L6482 belongs to a series of motor controllers and drivers from STMicroelectronics. It is part of the cSPIN family, which includes variants like the L6480. These devices are designed to simplify motor control by integrating the gate driver, motion engine, and protection circuits into a single package.

Replacement Considerations

The L6480 is a related part within the same series. Verify pinout compatibility and functional differences between the L6482 and L6480 if considering substitution. Check datasheet specifications for both parts to ensure electrical parameters meet the application requirements.
