UC3638N

Motor Drivers, Controllers Overview

The UC3638N is an advanced PWM motor controller manufactured by Texas Instruments, designed for brushed DC motor applications. It operates within a supply voltage range of 10 V to 36 V and delivers an output current of 500 mA. The device features a full bridge configuration with a quiescent supply current of 15 mA. It supports through-hole installation in a PDIP-20 package and functions reliably across an operating temperature range of 0°C to +70°C.

Motor Drivers, Controllers Feature Summary

• Advanced PWM control architecture for precise motor management
• Integrated full bridge driver topology for bidirectional operation
• Built-in direction management and commutation control logic

Motor Drivers, Controllers Applications

• Brushed DC motor speed and direction control systems
• Industrial motion control circuits
• Automotive ignition and motor driver modules

Motor Drivers, Controllers Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 through-hole package variant. Confirm RoHS compliance status via the official datasheet as indicated in distributor listings. Ensure the application environment remains within the specified 0°C to +70°C thermal limits. Validate that the 10V to 36V supply range matches system requirements before integration.

Motor Drivers, Controllers Selection Notes

Select this component when a through-hole solution is required for brushed DC motor control. The PDIP-20 package facilitates manual assembly or wave soldering processes. Compare against surface mount variants like the DWTR if PCB space constraints dictate SMD technology. Ensure the 500 mA output capability meets the load requirements without external heat sinking.

Motor Drivers, Controllers Part Context

This part belongs to the UC3638 series of advanced PWM motor controllers from Texas Instruments. It shares functional similarities with the UC2638 but offers extended voltage capabilities up to 36 V. The series is categorized under PMIC motor drivers, providing integrated solutions for commutation and direction management in industrial and automotive sectors.

Motor Drivers, Controllers Replacement Considerations

The UC2638DW serves as a direct substitute for the UC3638DW in surface mount designs. For through-hole replacements, verify pin compatibility with other PDIP-20 motor controllers. Cross-reference electrical specifications to ensure voltage and current ratings align with the original design intent.
