L6204D

Full Half-Bridge (H Bridge) Drivers Overview

The L6204D is a discontinued four-channel half-bridge driver manufactured by STMicroelectronics, designed for DC motor and general-purpose applications. It utilizes BCDMOS technology to provide robust power switching capabilities within a compact 28-SOIC package. The device supports a supply voltage range of 2V to 7V and handles load voltages from 12V to 48V. Each channel delivers a continuous output current of 500mA with a peak current capacity of 3A. The typical on-resistance is 1.2 ohms, ensuring efficient power management. It operates reliably across a junction temperature range of -40°C to 150°C.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify component authenticity through authorized channels as the L6204D is officially obsolete. Confirm RoHS3 compliance status and check for moisture sensitivity level 1 handling requirements during storage. Ensure replacement strategies are evaluated due to end-of-life status. Validate that the 28-SO package dimensions match existing PCB footprints before finalizing any legacy design modifications.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component only for legacy maintenance or specific non-critical designs where the 28-SO package and 48V load capability are required. Consider the discontinuation status when planning long-term production cycles. Evaluate alternative drivers if new designs are initiated, as availability is limited. Ensure interface logic compatibility with the controlling microcontroller is verified prior to integration.

Full Half-Bridge (H Bridge) Drivers Part Context

The L6204 belongs to STMicroelectronics' broader portfolio of DMOS motor drivers, which includes full-bridge variants like the L6203 and L6205. This series is engineered for industrial and consumer applications requiring reliable power switching. The L6204 specifically addresses needs for multiple independent half-bridge outputs, distinguishing it from single or dual bridge solutions in the same family.
