L6205N

Overview

The L6205N 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 a single chip. The device supports an operating supply voltage range from 8 V to 52 V and delivers a peak output current of 5.6 A, with a continuous DC current rating of 2.8 A. It features a typical RDS(ON) of 0.3 Ω at Tj = 25 °C and operates at frequencies up to 100 kHz. The component includes integrated fast free-wheeling diodes, under-voltage lockout, cross-conduction protection, non-dissipative overcurrent protection, and thermal shutdown.

Feature Summary

• Integrates isolated DMOS power transistors with CMOS and bipolar circuits using MultiPower-BCD technology
• Provides non-dissipative overcurrent protection and thermal shutdown capabilities
• Features integrated fast free-wheeling diodes and under-voltage lockout mechanisms

Applications

• Brushed DC motor control systems
• Industrial automation equipment
• General-purpose motor drive circuits

Procurement Notes

Verify the package type matches project requirements, as the L6205 series includes PowerDIP20, PowerSO20, and SO20 variants. Confirm that the specific N suffix corresponds to the desired through-hole installation format. Ensure compatibility with the system's voltage range and thermal management needs given the 52 V maximum rating. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component for applications requiring robust open-loop brushed DC motor control where stability and anti-interference are prioritized over minimal power consumption. The BiCDMOS technology offers low temperature drift compared to pure MOSFET solutions. Consider the 2.8 A DC current limit and 52 V supply range when sizing the motor load. Evaluate the need for parallel operation support if higher current capacity is required beyond the single-chip limits.

Part Context

The L6205 belongs to the STSPIN L62 family of motor drivers. It is part of a broader line including variants like the L6205PD and L6205D, which differ primarily in packaging and mounting style. The L6205N specifically denotes the through-hole PDIP package version. This series is characterized by its use of MultiPower-BCD technology, distinguishing it from newer low-voltage or high-frequency specialized drivers in the STSPIN portfolio.
