UC2950T

Overview

The UC2950T is a half-bridge bipolar switch gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 8 V to 35 V and delivers an output current of 4 A. The device features non-inverting configuration with rise and fall times of 500 ns each. It supports CMOS and TTL logic inputs, draws 36 mA of operating supply current, and dissipates up to 2 W of power. Designed for through-hole mounting in a TO-220-5 package, it functions reliably between -20°C and +100°C.

Feature Summary

• Provides half-bridge drive capability for bipolar switches
• Compatible with standard CMOS and TTL logic families
• Includes internal protection against excessive power dissipation

Applications

• Driving IGBTs in power conversion circuits
• Controlling MOSFETs in switching applications
• Bipolar switch interface modules

Procurement Notes

Verify the specific suffix 'T' indicates the tube packaging format as documented. Confirm the TO-220-5 pinout matches the target PCB footprint. Ensure the application environment stays within the specified -20°C to +100°C operating temperature range. Check that the supply voltage remains strictly between 8 V and 35 V to prevent damage.

Selection Notes

Select this component when a single-channel half-bridge driver with 4 A peak output is required. It is suitable for designs needing direct compatibility with CMOS or TTL control signals. Consider the TO-220-5 package for through-hole assembly requirements. Evaluate thermal management needs based on the 2 W power dissipation rating under load conditions.

Part Context

This part belongs to the UC2950 series of gate drivers from Texas Instruments. It is categorized under PMIC and specifically IGBT/MOSFET gate drivers. The device serves as a standalone driver solution for medium-power switching applications requiring robust bipolar switch control capabilities.

Replacement Considerations

The UC2950TG3 is listed as an alternative variant with identical electrical specifications but potentially different environmental compliance status.
