Input voltage4.7-5.2 V
Output 112.5 V / 0.35 A
IC revisionE1

Description

The TIDA-01159 design provides a reference solution for half-bridge isolated gated drivers used in driving power stages of UPS, inverters, server and telecomapplications.This TI Design is based on the UCC21520 reinforced insulated gate driver from TI, and is capable of driving MOSFETs and SiC-FETs. The reference design contains a built-in isolated push-pull auxiliary powersupply for powering the output of the isolated gate driver.By bringing together the isolated gate driver and isolated power supply in a compact board with a form factor (30 mm × 35 mm), this reference design provides a fully tested robust half-bridge driver solution, capable of withstanding >100 kV/μs commonmodetransient immunity (CMTI).

Features

Compact Gate Drive Solution for Driving PowerStages Used in Mid- and High-Voltage PowerConverters, Single-Phase and Three-PhaseInverters Operating From AC Input Voltage Range(100- to 690-V AC)

  • High Driving Current (4-A Source and 6-A Sink)Suits Driving MOSFET / IGBT / SiC-FET WithCurrents up to 100 A and Operating Frequenciesup to 2 MHz, Reducing Switching LossesSignificantly
  • Supports 3250-VPK and 3000-VRMS Basic Isolation
  • Provides Very High CMTI of > 100 kV/μs forRobust Operation in Noisy Environments
  • Flexible and Configurable Solution as a Dual Low-Side, Dual High-Side, High-Side/Low-Side, or Half-Bridge Driver
  • Built-in Compact, High Efficient Isolated Supply toPower Output Side of Gate Driver
  • Integrated Dead-Time in Gate Driver ImprovesReliabilityREMARK:BOM is added with EVM board.

Typical applications

  • Energy Storage Banks,Battery Management Systems
  • Uninterruptible Power Supplies (UPS),Industrial Power Supplies
  • Server PSUs and Telecom Rectifiers
