Full Half-Bridge (H Bridge) Drivers Procurement Notes

The L6202 is officially classified as obsolete by STMicroelectronics. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Ensure that any available units match the original specifications and package types. Replacement strategies should prioritize verified substitute part numbers rather than relying on obsolete inventory availability.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component only if legacy compatibility is required, as it is no longer in production. Consider modern alternatives within the STSPIN series for new designs. Verify that the 42V supply voltage and 1.5A RMS current ratings meet system requirements. Check package availability, as options may be limited due to obsolescence status.

Full Half-Bridge (H Bridge) Drivers Part Context

The L6202 was historically significant as the first BCD super-integrated circuit, pioneering the combination of Bipolar, CMOS, and DMOS technologies on a single chip. This innovation earned recognition from the IEEE Milestones program in 2021 for its contribution to power integrated circuits. It laid the foundation for subsequent automotive, computer, and industrial applications utilizing BCD technology.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Public confirmed substitutes include the L6201, L6203, and L6207. These devices share similar DMOS full bridge architectures but differ in current ratings and additional features like PWM controllers. Verify pinout compatibility and electrical parameters before substitution.
