If you are looking for a brushless DC or stepper motor controller, this is not the part — the DRV8811PWPR, for example, handles bipolar steppers and has a wider temperature range (-40°C to 150°C), but it is a fully integrated driver with a different pinout and supply (8 V load). Stick with the UC3637DWTR for simple brushed DC direction and speed control where you already have the power FETs on the board. ## Lifecycle and sourcing reality This part is still a valid BOM line for new designs and production builds.","metaTitle":"UC3637DWTR Brushed DC Motor Controller, 2.5V-20V, 20-SOIC","metaDescription":"UC3637DWTR brushed DC motor controller from Texas Instruments.
