Product Overview
The L6201PSTR is a monolithic full-bridge motor driver from STMicroelectronics built on BCD technology. It integrates DMOS power switches and CMOS logic in one chip, beating the efficiency limits of classic bipolar drivers.
Supporting 12–48V supply, it delivers 2A continuous RMS current with 4A peak transient output for brushed DC and single-phase stepper motors. Low RDS(ON)cuts power loss, while built-in thermal shutdown, charge pump and cross-conduction lockout ensure stable operation.
Housed in thermally enhanced PowerSO-20 with exposed cooling pad, it suits industrial robots, medical pumps and office automation equipment.
Core Advantages
Advanced Monolithic DMOS Output Stage
Utilizes advanced DMOS power transistors with exceptionally low internal resistance, maximizing power conversion efficiency and drastically shrinking power losses compared to traditional bipolar drivers.
Exceptional Thermal Management Layout
Packaged in a high-density PowerSO-20 enclosure equipped with an integrated bottom-side exposed metal slug, facilitating efficient thermal dissipation into the system ground plane to support continuous heavy-duty cycles.
High Switching Frequency & Efficiency
Supports rapid switching speeds up to 100 kHz, allowing for smooth, low-noise PWM current regulation and precise motor position/torque tracking while avoiding audible frequency hums.
Robust Internal System Safeguards
Features built-in autonomous protection sub-blocks including thermal shutdown, under-voltage lockout (UVLO), and dynamic cross-conduction interlocks to prevent catastrophic field failures.

Frequently Asked Questions
Q1: Is your currently available stock of the L6201PSTR driver chip 100% genuine and original?
A: Yes, we guarantee that all L6201PSTR devices in our inventory are 100% brand-new, factory-original products from STMicroelectronics. They are logged, managed, and shipped strictly inside moisture-controlled, anti-static ESD shielding pipelines.
Q2: What does the “TR” suffix indicate in the orderable part number L6201PSTR?
A: The “TR” suffix indicates that the components are delivered in Tape and Reel format. This packaging configuration is ideal for automated high-speed SMD pick-and-place systems used on volume electronic manufacturing assembly lines.
Q3: Why is cross-conduction protection critical, and how does the L6201PSTR handle it?
A: Cross-conduction occurs if both the top and bottom transistors of an H-bridge turn on at the same time, causing a catastrophic short-circuit across the supply rails. The L6201PSTR includes built-in hardware dead-time logic that prevents this condition by ensuring one transistor is fully off before its bridge complement activates.
Q4: How can our engineering development group request reflow soldering thermal land designs or ask for high-volume pricing scales?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
