L6234PD013TR

Overview

The L6234PD013TR is a three-phase brushless DC motor driver manufactured by STMicroelectronics. It utilizes BCDmultipower technology to integrate isolated DMOS power transistors with CMOS and bipolar circuits on a single chip, optimizing logic and power stage performance. The device operates within a supply voltage range of 7 V to 52 V and supports peak currents up to 5 A. It features an RDSon of 0.3 Ω at 25 °C and functions at frequencies up to 150 kHz. The component is housed in a 20-pin PowerSO package and includes thermal shutdown protection.

Feature Summary

• Integrates isolated DMOS power transistors with CMOS and bipolar circuits via BCDmultipower technology for optimized performance
• Provides cross-conduction protection and intrinsic fast free-wheeling diodes for reliable operation
• Features TTL, CMOS, and microprocessor compatible logic inputs with separate control for each channel

Applications

• Driving three-phase brushless DC motors
• Industrial motion control systems
• Automotive ignition controllers

Procurement Notes

Verify the specific suffix PD013TR confirms the tape and reel packaging format required for automated assembly processes. Confirm that the operating temperature range and voltage specifications align with the target application's environmental constraints before finalizing procurement decisions.

Selection Notes

Select this component when a triple half-bridge configuration is required for BLDC applications. Consider the 20-pin PowerSO package for space-constrained designs. Ensure the thermal management solution accommodates the RMS current limits defined by the package dissipation capability rather than just the peak current rating.

Part Context

This part belongs to the L6234 series of three-phase motor drivers from STMicroelectronics. It is designed specifically for driving brushless DC motors using a triple half-bridge topology. The device is distinct from other series members by its specific integration of DMOS technology and its compatibility with standard logic families.

Replacement Considerations

Direct substitutes within the same family include the L6234PD (tube packaging) or L6234PDT (tape and reel). Verify pinout compatibility and electrical parameters when considering alternative packages or manufacturers.
