It targets general-purpose brushless DC motor applications where the load voltage and supply rail share a common 12 V to 52 V range. Rated for 1.4 A continuous output current per phase, the driver uses ST's BiCDMOS process to integrate the DMOS power transistors with bipolar and CMOS control circuitry on the same die. Operating junction temperature spans -25°C to 125°C. ## What the 1.4 A and 52 V ratings mean for your BOM The 1.4 A continuous output rating is the per-phase current the half-bridge can sustain under normal operating conditions — not a peak surge figure. For a BLDC motor with a 1 A RMS phase current at 48 V, the L6229PDTR runs within its continuous envelope with headroom for startup inrush. The 12 V to 52 V common supply and load voltage range means a single 48 V battery or a 24 V industrial rail powers both the logic and the motor without a separate regulator. The parallel interface accepts step/direction or PWM signals from a host MCU. ROHS3 compliant — no exemptions for lead in solder or other restricted substances under the current directive. ## How it compares to the L6229DTR The L6229DTR is electrically identical — same 1.4 A output, same 12 V to 52 V range, same half-bridge configuration. The difference is packaging: the L6229PDTR ships in a PowerSO-36 with an exposed pad for better thermal dissipation, while the L6229DTR uses a standard PowerSO-36 without the exposed pad. For a board already laid out for the L6229DTR, the L6229PDTR will not drop in without a PCB change to accommodate the pad.","metaTitle":"STMicroelectronics L6229PDTR BLDC Motor Driver, 1.4A, 12-52V","metaDescription":"STMicroelectronics L6229PDTR STSPIN L62 BLDC motor driver, 1.4A output, 12-52V, BiCDMOS, PowerSO-36.
