L6230PDTR

Overview

The L6230PDTR is a fully integrated three-phase brushless DC motor driver manufactured by STMicroelectronics. It utilizes DMOS technology within a PowerSO-36 package to combine isolated power transistors with CMOS and bipolar control circuits. The device supports an operating supply voltage range of 8 V to 52 V and delivers a peak output current of 2.8 A, with an RMS rating of 1.4 A. It features a typical on-resistance (RDS(ON)) of 0.73 Ω at 25 °C junction temperature. Designed for Field-Oriented Control (FOC) applications, it includes independent current sensing capabilities, non-dissipative overcurrent protection, thermal shutdown, and undervoltage lockout.

Feature Summary

• Fully integrated three-phase motor driver optimized for Field-Oriented Control (FOC) applications through independent current sensing.
• Combines isolated DMOS power transistors with CMOS and bipolar circuits on a single chip using BCD technology.
• Includes comprehensive protection mechanisms such as non-dissipative overcurrent detection, cross-conduction protection, and thermal shutdown.

Applications

• Field-Oriented Control (FOC) of three-phase brushless DC motors
• Evaluation of PMSM motor control algorithms using development platforms
• Industrial motor control systems requiring integrated power and logic

Procurement Notes

Verify the specific suffix 'PDTR' corresponds to the PowerSO-36 package and tape-and-reel packaging configuration. Confirm that the component meets the required industrial temperature grade specifications. Ensure compatibility with the intended PCB footprint for the PowerSO-36 Slug Up variant. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a fully integrated solution for three-phase BLDC or PMSM motors is required. It is suitable for designs needing FOC optimization via independent current sense outputs. Consider the 8 V to 52 V supply range and 2.8 A peak current capability against load requirements. Evaluate the PowerSO-36 package for thermal management needs in the target application environment.

Part Context

The L6230PDTR belongs to the L6230 series of motor drivers from STMicroelectronics. This series is characterized by its integration of power and control stages for three-phase motor applications. The PDTR suffix specifically denotes the reel packaging format for the PowerSO-36 version, distinguishing it from other package options like VFQFPN available in the same family.
