L6460TR

Overview

The L6460TR is a fully integrated bipolar stepper and DC motor driver manufactured by STMicroelectronics, housed in a 64-TQFP-EP package. It operates within a supply voltage range of 13V to 38V and supports step resolutions from full step to 1/16 microstepping. The device features an SPI interface for configuration and includes built-in thermal warning, overcurrent protection, and undervoltage lock-out. Designed for surface mount installation, it functions across a junction temperature range of -40°C to 125°C.

Feature Summary

Integrates control logic, power stage, and auxiliary features for multi-motor systems
Supports simultaneous driving of two DC motors and one bipolar stepper motor
Includes programmable watchdog, ADC, operational amplifiers, and PWM generators

Applications

Multi-motor system control architectures
Bipolar stepper motor positioning applications
Brushed DC motor drive implementations

Procurement Notes

Verify component authenticity through authorized channels as the L6460TR is listed as obsolete. Confirm package integrity and pin alignment against the 64-TQFP-EP specification before integration. Ensure design compatibility with the 13V to 38V operating range and SPI communication protocols required for proper initialization and fault monitoring.

Selection Notes

Select this component for designs requiring high integration of motor control and power delivery in a single IC. It is suitable for applications needing configurable microstepping and multiple motor types. Consider the obsolete status when planning long-term production runs. Evaluate the need for its specific auxiliary peripherals like ADCs and comparators against alternative discrete solutions.

Part Context

The L6460 belongs to STMicroelectronics' portfolio of advanced motor drivers optimized for complex multi-motor environments. It distinguishes itself by combining bridge drivers with embedded regulators and signal processing units. This integration reduces external component count and simplifies PCB layout for industrial and automotive automation systems requiring precise motion control.
