L6207D

Full Half-Bridge (H Bridge) Drivers Overview

The L6207D is a DMOS dual full bridge motor driver designed for DC and stepper motor control applications. It integrates two independent constant off-time PWM current controllers for chopping regulation. The device operates with a supply voltage range of 8V to 52V, delivering a peak output current of 5.6A (2.8A DC) per channel. Key electrical parameters include a typical on-resistance of 0.3Ω at Tj=25°C and an operating frequency up to 100kHz. It features non-dissipative overcurrent protection, thermal shutdown, undervoltage lockout, and cross-conduction protection.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific package variant required, as the L6207 family includes both PowerSO-36 and SO24 options. Confirm RoHS compliance status and REACH SVHC declarations against current regulatory requirements. Ensure the selected suffix matches the desired tape-and-reel or tube packaging configuration for manufacturing integration.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when dual full-bridge control with integrated PWM current regulation is required. The L6207D is suitable for applications needing high peak currents and robust protection features. Consider the PowerSO-36 package for superior thermal dissipation in high-power scenarios compared to standard SOIC packages.

Full Half-Bridge (H Bridge) Drivers Part Context

The L6207 belongs to STMicroelectronics' L62xx series of DMOS dual full bridge drivers. This series utilizes BCD technology to combine isolated DMOS power transistors with CMOS and bipolar circuits. The L6207 specifically distinguishes itself by incorporating built-in PWM current controllers, unlike variants such as the L6205 or L6206 which lack this feature.
