STMicroelectronics, Inc. Motor Drivers, Controllers L6460TR

The L6460TR is a highly configurable motor driver designed for multi-motor applications, capable of driving both stepper and DC motors. It operates with a supply voltage range of 13 V to 38 V and features four full bridge drivers that can be configured for various motor architectures, including the ability to drive up to two DC motors and one stepper motor simultaneously, or four DC motors. The device includes auxiliary features such as a 9-bit ADC, operational amplifiers, a digital comparator, and multiple GPIOs, enhancing its versatility in control applications. The L6460TR integrates several power management functions, including switching buck regulators and a battery charger, while ensuring robust protection mechanisms like thermal shutdown, overcurrent protection, and undervoltage lock-out. It supports an SPI interface for configuration and control, and includes a programmable watchdog function for added reliability. The device is packaged in a TQFP64 format and is suitable for applications requiring efficient motor control with a high degree of integration and customization.
