UCC3750N

Telecom Overview

The UCC3750N is a source ringer controller manufactured by Texas Instruments, designed for four-quadrant flyback-based ring generator circuits. It operates on a 5 V supply with a typical current consumption of 500 uA. The device supports frequencies of 20 Hz, 25 Hz, and 50 Hz. It is housed in a 28-pin PDIP package and functions within an operating temperature range of 0°C to +70°C. The component includes DC current limiting and secondary side voltage mode control features.

Telecom Feature Summary

• Provides complete control and drive solution for four-quadrant flyback-based ring generator circuits
• Integrates DC current limiting functionality
• Utilizes secondary side voltage mode control

Telecom Applications

• Telecommunications equipment requiring source ringer control
• Four-quadrant flyback ring generator designs
• Communication ICs for tone generation

Telecom Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the 28-pin PDIP form factor aligns with your PCB layout requirements. Ensure the operating temperature range meets your environmental specifications. Check for any lead-free or RoHS compliance markings if required by your manufacturing standards.

Telecom Selection Notes

Select this component when a dedicated controller for flyback-based ring generators is needed. It is suitable for applications requiring precise frequency selection at 20 Hz, 25 Hz, or 50 Hz. Consider the 28-pin PDIP package for through-hole mounting needs. Evaluate the 500 uA supply current against system power constraints.

Telecom Part Context

The UCC3750N belongs to the UCC3750 family of communication ICs from Texas Instruments. It serves as a specialized telecom circuit for generating ringing signals. Related variants include the SOIC-28 packaged versions such as UCC3750DW. The N suffix denotes the PDIP package option within this product line.

Telecom Replacement Considerations

Public documentation indicates the UCC3750N has been replaced by newer iterations. Verify compatibility with successor parts like the UCC3750DW series if transitioning to surface mount technology. Ensure functional equivalence regarding the four-quadrant flyback control architecture.
