L6205PD

Overview

The L6205PD is a DMOS Dual Full Bridge driver designed for motor control applications, realized in MultiPower-BCD technology. It integrates isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device operates within an operating supply voltage range of 8 V to 52 V. It provides a typical RDS(ON) value of 0.3 Ω at Tj = 25 °C, supporting a peak output current of 5.6 A and a continuous DC output current of 2.8 A. The component supports operating frequencies up to 100 kHz and features thermal shutdown protection.

Feature Summary

• Integrates non-dissipative overcurrent protection and thermal shutdown mechanisms.
• Features fast free-wheeling diodes under voltage lockout conditions.
• Includes cross-conduction protection to prevent simultaneous switching.
• Supports paralleled operation for increased current handling capabilities.

Applications

• Brushed DC motor control systems
• Industrial automation equipment
• Single-phase electricity meter actuators

Procurement Notes

Verify the specific package variant, as the L6205 series includes PowerSO-20, SO-20, and PowerDIP-20 options. Confirm that the PD suffix corresponds to the PowerSO-20 surface-mount package required for the design. Ensure compatibility with the intended PCB footprint and soldering profile for the selected package type before finalizing procurement orders.

Selection Notes

Select this component when a dual full bridge configuration is required for brushed DC motors within the 8 V to 52 V supply range. The 2.8 A continuous current rating suits moderate load applications. Consider the integrated protection features for robust industrial environments. Evaluate the PowerSO-20 package for thermal performance and space constraints compared to through-hole alternatives.

Part Context

The L6205 belongs to STMicroelectronics' L62xx series of DMOS dual full bridge drivers. This family is part of the broader STSPIN product line focused on motor control solutions. The L6205 serves as a foundational driver IC, offering high integration by combining power stages and logic controls on a single BiCDMOS chip for efficient system design.
