Product Description
STMicroelectronics L6470HTR Stepper Motor Driver IC is an advanced fully integrated microstepping driver designed for driving two-phase bipolar stepper motors. Packaged in a compact 28-pin HTSSOP28 surface-mount package, this device operates over a wide voltage range from 8V to 45V, supporting peak output currents of up to 7.0A and continuous RMS output current of 3.0A.
This driver features an embedded motion engine capable of programmable speed profile and precise positioning, controlled via an SPI interface. It incorporates low RDSon power MOSFETs, which improve power efficiency and reduce heat dissipation, making it ideal for compact industrial designs.
With microstepping resolution up to 1/128 step, the L6470HTR delivers smooth and accurate motor motion. Additional features include sensorless stall detection, programmable MOS slew rate, and non-dissipative over current protection on both high and low sides, enhancing motor reliability and safety.
The device supports operation in harsh environments with a wide operating temperature range of -40°C to 150°C. RoHS compliance ensures it meets environmental regulation standards.
This motor driver IC is well-suited for use in industrial automation, robotics, laboratory instrumentation, HVAC systems, and manufacturing equipment requiring precise motor control.
Operates over 8V to 45V supply voltage range. Maximum output current 3A continuous RMS, 7A peak. 28-pin HTSSOP28 surface mount package. Programmable microstepping up to 1/128 step resolution. SPI interface for configuration and control.
Sensorless stall detection enhances motor protection. Low quiescent and standby current consumption. RoHS compliant for environmental safety.
