It outputs a pre-driver signal to external half-bridge MOSFETs (two half-bridges), so the actual power stage is off-chip. The parallel interface accepts logic-level direction and PWM commands, making it a straightforward fit for PLC-driven or microcontroller-supervised axis control. Supply range of 10V to 36V covers 12V and 24V industrial bus voltages without an extra regulator. Operating temperature is 0°C to 70°C, so this part is specced for indoor control cabinets, not for under-hood or outdoor enclosures. Package is a 20-SOIC wide-body (7.50 mm width), surface-mount. Tube shipment suits engineering samples and low-volume builds; for reel quantities, confirm the order code suffix with your distributor. ## Pre-driver vs integrated driver — what it means for your BOM The UC3638DW is a controller-only IC: it generates gate-drive signals but needs external N-channel MOSFETs and bootstrap circuitry to switch motor current. That gives you flexibility to size the FETs for the actual motor load, but adds board area and BOM lines. ## Active lifecycle, no LTB watch needed The UC3638DW carries an Active product status and is ROHS3 compliant. For a BOM line that needs a brushed DC pre-driver with a wide supply range, this part is safe to qualify into new production without an obsolescence contingency plan.","metaTitle":"UC3638DW Motor Driver IC, 10V-36V, 20-SOIC","metaDescription":"UC3638DW brushed DC motor pre-driver, 10V-36V supply, parallel interface, 20-SOIC package.
