E-L6201PSTR

Full Half-Bridge (H Bridge) Drivers Overview

The L6201PSTR is a DMOS full bridge driver for motor control applications, manufactured by STMicroelectronics in a PowerSO-20 surface-mount package. It utilizes Multipower-BCD technology to combine isolated DMOS power transistors with CMOS and Bipolar circuits. The device supports supply voltages from 12 V to 48 V and delivers a maximum peak current of 2 A with a total RMS current of 1 A. Key electrical parameters include a typical on-resistance (RDS(on)) of 0.3 Ω at 25 °C, an operating frequency up to 100 kHz, and a quiescent supply current of 15 mA. It operates within a junction temperature range of -40 °C to +150 °C.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'PSTR' corresponds to the reel packaging format required for your assembly line. Confirm that the PowerSO-20 footprint matches your PCB design guidelines. Ensure compatibility with the 12 V to 48 V supply voltage range for your target application. Check moisture sensitivity level (MSL 3) requirements for storage and reflow soldering processes.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a single-chip solution for brushed DC motors is needed with high efficiency and robust protection features. The 2 A peak current rating suits moderate load applications. Consider the PowerSO-20 package for its thermal performance in surface-mount designs. Verify that the 0.3 Ω RDS(on) meets your power dissipation constraints.

Full Half-Bridge (H Bridge) Drivers Part Context

The L6201PSTR belongs to the L620x series of DMOS full bridge drivers from STMicroelectronics. This series includes variants like L6202 and L6203 with different current ratings. The PSTR suffix indicates a tape-and-reel packaging option, distinct from tube-packaged versions like L6201PS. All variants share the same core Multipower-BCD technology and functional architecture.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Direct substitutes within the same family include L6202 and L6203, which offer higher current capabilities but maintain similar pinouts and functionality. For lower current needs, verify if other series components meet the voltage and interface requirements without compromising performance.
