UCC3751N

Telecom Overview

The UCC3751N is a single-line ring generator controller manufactured by Texas Instruments. It is designed to drive external MOSFETs or bipolar transistors in a half-bridge configuration to generate ring voltages up to ±90V. The device operates within a supply voltage range of 10V to 24V and supports an operating temperature range from 0°C to +70°C. It is housed in a 16-pin PDIP package.

Telecom Feature Summary

• Generates ring voltages up to ±90V for single-line applications
• Drives external MOSFETs or bipolar transistors in a half-bridge configuration
• Operates with supply voltages between 10V and 24V

Telecom Applications

• Single-line telephone systems
• Ring generator circuits
• Telecommunications equipment

Telecom Procurement Notes

Verify the specific package type, as the UCC3751N designation typically refers to the 16-PDIP variant, while other suffixes may indicate different packages. Confirm that the application requires the ±90V output capability and half-bridge drive architecture. Ensure the operating environment stays within the 0°C to +70°C temperature range. Check datasheet specifications for external component requirements to support the driver stage.

Telecom Selection Notes

Select this component when designing single-line ring generators requiring high-voltage output up to ±90V. It is suitable for driving external power switches in a half-bridge topology. Consider the 16-PDIP package if through-hole mounting is required. Verify compatibility with the target supply voltage range of 10V to 24V. This controller is intended for telecommunications applications rather than general-purpose audio amplification.

Telecom Part Context

The UCC3751N belongs to the UCC37xx series of communication ICs from Texas Instruments. These components are specialized controllers for generating ringing signals in telephone systems. Unlike standard audio amplifiers, this part focuses on high-voltage pulse generation for line signaling. It serves as a dedicated solution for ringers in single-line configurations.
