L6205D

Overview

The L6205D is a DMOS dual full-bridge motor driver manufactured by STMicroelectronics, designed for brushed DC and bipolar stepper motor control. It utilizes MultiPower-BCD technology to integrate isolated DMOS power transistors with CMOS and bipolar circuits on a single chip. The device operates within an 8V to 52V supply voltage range and provides a peak output current of 5.6A, with a continuous DC current rating of 2.8A. It features a typical RDS(on) of 0.3Ω at Tj = 25°C and supports operating frequencies up to 100kHz. The component is housed in a 20-SOIC package.

Feature Summary

• Integrates non-dissipative overcurrent protection and thermal shutdown mechanisms for robust operation.
• Includes integrated fast free-wheeling diodes and cross-conduction protection circuitry.
• Supports paralleled operation for enhanced current handling capabilities.

Applications

• Brushed DC motor control systems
• Bipolar stepper motor drives
• Industrial automation equipment

Procurement Notes

Verify the specific suffix 'D' indicates the SOIC package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements against project specifications. Ensure the supplier documentation matches the exact part number to avoid confusion with other package types like PowerSO or DIP variants within the same product family.

Selection Notes

Select this component for applications requiring high peak current capability and integrated protection features. Consider the 20-SOIC package constraints regarding thermal dissipation and PCB layout. Evaluate the need for paralleled operation if higher continuous current than 2.8A is required. Verify that the 52V maximum supply voltage aligns with the system power architecture.

Part Context

The L6205 belongs to the L6205 series of DMOS dual full-bridge drivers from STMicroelectronics. This series is engineered for general-purpose motor control applications using MultiPower-BCD technology. The L6205D specifically denotes the standard SOIC package version, distinct from the PowerSO or PowerDIP variants available in the broader product line.

Replacement Considerations

• L6205PD
• L6205N
