Active-production brushed DC motor driver for automotive loads
The Infineon TLE4209GXUMA2 is a fully integrated driver that combines control logic and power stage in a single 14-SOIC package — no external FETs needed for small brushed DC or DC servo motors. It's rated for 700 mA continuous output per half bridge, with the supply and load voltage both running from an 8 V to 18 V rail, which covers the nominal 12 V automotive bus including cold-crank dips and load-dump recovery transients. The part is officially Active on the lifecycle and ROHS3 Compliant, so there's no last-time-buy panic — it's still a valid BOM entry for new and existing designs. The automotive application grade means the silicon is built and screened for the thermal and vibration profile of vehicle electronics, not just commercial or industrial ambient conditions.
What the 700 mA and 150 °C junction rating mean for fit
The 700 mA output current is the continuous per-channel rating at the half-bridge outputs — this is the number to size against your motor's locked-rotor or stall current, not just the running current. For a small HVAC flap actuator or a coolant valve that draws 400 mA steady but spikes to 1 A on start, the TLE4209GXUMA2 needs external current limiting or a derating check against the 14-SOIC's thermal impedance. The junction temperature range runs from -40 °C to 150 °C, which is the full automotive Grade 1 band. That 150 °C upper limit is the silicon junction, not the case — the actual output current you can sustain at 125 °C ambient under the hood will be lower than the 700 mA at 25 °C.
Package and board-fit for the 14-SOIC footprint
The 3.90 mm width is the narrow SOIC variant — the pad pitch is 1.27 mm, which is a standard two-layer-board-friendly footprint. The exposed pad underneath is the thermal and electrical ground connection; the layout should tie it to the ground plane with multiple vias to keep the junction temperature in check during sustained motor drive. Available in Tape & Reel (TR) or Cut Tape (CT) — the reel quantity is the standard 2,500-piece reel for 14-SOIC, which covers medium-volume production runs without reel changeovers. For prototype or low-volume builds, the cut tape option avoids buying a full reel.
