UC3637QG3

Motor Drivers, Controllers Overview

The UC3637QG3 is a switched-mode controller for brushed DC motors, manufactured by Texas Instruments. It operates within a supply voltage range of 5 V to 36 V and draws a typical quiescent current of 8.5 mA. The device is housed in a PLCC-20 surface-mount package and is rated for an operating temperature range from 0°C to +70°C. Classified under PMIC - Power Management ICs, it functions as a PWM motor controller designed for motion control applications.

Motor Drivers, Controllers Feature Summary

• Integrated switched-mode control architecture for efficient brushed DC motor operation
• Supports pulse-width modulation (PWM) techniques for precise speed regulation
• Designed for surface-mount installation in compact electronic assemblies

Motor Drivers, Controllers Applications

• Brushed DC motor speed control systems
• General motion control circuits
• Industrial automation equipment requiring low-power motor drivers

Motor Drivers, Controllers Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details via the official datasheet. Check humidity sensitivity handling requirements before assembly. Ensure the PLCC-20 footprint matches the design layout. Validate that the commercial temperature range meets system environmental needs.

Motor Drivers, Controllers Selection Notes

Select this component for applications requiring a dedicated switched-mode controller for brushed DC motors. The PLCC-20 package suits surface-mount designs. Consider the 5 V to 36 V input range for compatibility with standard power supplies. Evaluate the 0°C to +70°C operating limit against environmental conditions. Compare against other UC3637 variants if different packaging or extended temperature ranges are required.

Motor Drivers, Controllers Part Context

The UC3637QG3 belongs to the UC3637 series of motor controllers from Texas Instruments. This series focuses on providing integrated solutions for driving brushed DC motors using switched-mode techniques. The QG3 suffix typically denotes specific packaging and quality grades within the family, distinct from other variants like the DW or DWTR which may use different packages such as SOIC-20.
