L6230Q

Overview

The L6230Q is a fully integrated DMOS three-phase motor driver designed for brushless DC motors. It operates within an 8 V to 52 V supply range and delivers a 2.8 A peak output current, equivalent to 1.4 A RMS. The device features a typical on-resistance of 0.73 Ω at 25 °C and supports operating frequencies up to 100 kHz. Packaged in a VFQFPN-32 format, it includes integrated fast freewheeling diodes and functions reliably across temperatures from -25 °C to +125 °C.

Feature Summary

• Optimized for Field-Oriented Control (FOC) applications through independent current sensing capabilities.
• Features non-dissipative overcurrent protection on high-side power MOSFETs combined with thermal shutdown.
• Integrates cross-conduction protection and diagnostic outputs for enhanced system reliability.

Applications

• Field-Oriented Control (FOC) systems for three-phase brushless DC motors
• Industrial automation equipment requiring precise motor control
• Home appliance drive circuits

Procurement Notes

Verify the specific suffix 'Q' against the manufacturer's latest documentation to confirm package type and compliance status. Ensure compatibility with the required mounting style and thermal management solutions. Confirm that the intended application voltage remains within the specified 8 V to 52 V operational limits. Check for any recent product change notices regarding availability or specifications.

Selection Notes

Select this component when FOC optimization and independent current sensing are required for three-phase BLDC applications. The VFQFPN-32 package suits space-constrained designs needing surface-mount integration. Consider the 1.4 A RMS current rating and 52 V maximum voltage for appropriate load matching. Evaluate thermal performance requirements given the integrated protection features.

Part Context

The L6230Q belongs to the L6230 series of DMOS drivers manufactured by STMicroelectronics. This series utilizes BCD multipower technology to combine isolated DMOS power transistors with CMOS and bipolar circuits. The Q variant specifically denotes the VFQFPN-32 package option, distinguishing it from other package types like PowerSO-36 available in the same family.
