Texas Instruments UCC21520 Half Bridge IGBT & MOSFET Driver SOIC-16

The Texas Instruments UCC21520 is a half-bridge gate driver with 6 A peak output current, designed to drive IGBT and MOSFET power switches.

Overview

The UCC21520 is a high-performance, isolated dual-channel gate driver for efficient control in power electronics applications. It supports both IGBT and MOSFET power switches. Its half-bridge configuration suits applications such as motor drives, solar inverters, and switched-mode power supplies (SMPS). The isolated design provides enhanced safety and noise immunity, helping to protect sensitive control logic from high-voltage transients on the power side.

Key Features

• Dual-channel design: Provides independent control for two output channels.
• Isolated gate drive: Offers electrical isolation between input and output for improved system safety and noise rejection.
• High-current capability: 6 A peak output current for driving large power switches.
• Wide operating range: Supply voltage from 6.5 V to 25 V and an operating temperature range from -40°C to 125°C.
• Surface-mount package: SOIC-16 footprint for compact, high-density PCB assembly.

Dimensions and Weight

The unit measures 3.3 (width) x 1.5 (depth) x 4.3 (height) and weighs 7.53 gm.

Applications

Suitable for motor drives, solar inverters, switched-mode power supplies, industrial automation, and automotive systems. Its extended temperature range supports operation in demanding environmental conditions.

This driver is a component for engineers seeking a high-speed interface between low-voltage control circuits and high-voltage power stages.
