L6230PD

Overview

The L6230PD is a fully integrated DMOS driver for three-phase brushless DC motors, manufactured by STMicroelectronics. It operates within an 8V to 52V supply range and delivers a peak output current of 2.8A (1.4A RMS). The device features independent current sensing optimized for Field-Oriented Control (FOC) and six-step algorithms. Integrated protections include non-dissipative overcurrent detection, cross-conduction protection, thermal shutdown, and undervoltage lockout. It utilizes PowerSO-36 surface-mount packaging.

Feature Summary

• Fully integrated DMOS technology combining isolated power transistors with CMOS and bipolar circuits on a single chip.
• Independent current sensing channels enabling precise control for FOC and six-step commutation algorithms.
• Comprehensive protection suite including non-dissipative overcurrent detection, cross-conduction prevention, and thermal shutdown.
• Integrated fast freewheeling diodes and diagnostic output capabilities for enhanced system reliability.

Applications

• Three-phase brushless DC motor control in HVAC systems
• Motor drive solutions for industrial power tools
• Field-oriented control (FOC) implementations for PMSM motors

Procurement Notes

Verify the specific suffix 'PD' corresponds to the PowerSO-36 tube package configuration when sourcing components. Confirm that the required operating temperature range aligns with the industrial grade specifications provided in the official datasheet. Ensure compatibility with the target voltage domain between 8V and 52V prior to integration into the final design architecture.

Selection Notes

Select this component for applications requiring high-efficiency three-phase motor driving with integrated protection features. The independent current sensing capability makes it suitable for advanced control strategies like FOC. Consider the PowerSO-36 package for surface-mount assembly requirements and verify thermal management needs based on the 1.4A RMS continuous current rating.
