L6201PS

Full Half-Bridge (H Bridge) Drivers Overview

The L6201PS is a DMOS full bridge driver for motor control applications, realized in Multipower-BCD technology. It combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip. The device features a supply voltage up to 48V, total RMS current of 4A, and max peak current of 5A. It operates at frequencies up to 100kHz with TTL compatible logic inputs. Key protections include cross-conduction protection and thermal shutdown. The typical RDS(ON) is 0.3 Ω at 25°C. It is housed in a 20-pin PowerSO package.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'PS' indicates the PowerSO-20 surface mount package configuration. Confirm that the 4A RMS current rating applies to your thermal management design, as this differs from the standard L6201 variant. Ensure compatibility with 12V to 48V supply ranges and check for moisture sensitivity handling requirements during assembly.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select the L6201PS when a 4A RMS current capability is required, distinguishing it from the lower-current L6201 (1A) and L6202 (1.5A) variants. Choose this component if a 20-pin PowerSO surface mount package is preferred over other available form factors. Ensure the application requires a single full bridge driver rather than dual bridge configurations found in other series members.

Full Half-Bridge (H Bridge) Drivers Part Context

The L6201PS belongs to the L6201 series of DMOS full bridge drivers from STMicroelectronics. This series utilizes Multipower-BCD technology to integrate power and logic functions. The PS suffix specifically denotes the PowerSO-20 package type, differentiating it from other pinout or packaging options within the broader L620x family designed for various motor control needs.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

L6201PSTR: Same functional specifications but in SOP-20 package. L6201: Lower RMS current (1A) but similar electrical characteristics. L6202: Higher RMS current (1.5A). Verify package footprint compatibility when substituting with non-PS variants.
