Product Introduction

Overview

The UCC27712D, produced by Texas Instruments, is a high-performance, dual-channel gate driver designed to drive high-side and low-side power MOSFETs or IGBTs in various power conversion applications. This device is part of TI's advanced high-voltage technology, offering robust drive capabilities with excellent noise and transient immunity. The UCC27712D features a floating channel for bootstrap or isolated power supplies, making it suitable for bridge topologies such as half-bridge, full-bridge, and LLC converters. It is fully operational up to 620 V and has a recommended VDD operating voltage range of 10 V to 20 V, with peak output currents of 1.8 A source and 2.8 A sink.

  • High-side and low-side configuration with a floating channel designed for bootstrap operation.
  • Peak output current of 1.8 A source and 2.8 A sink.
  • dv/dt immunity of 50 V/ns and large negative transient safe operating area (NTSOA) on the switch node (HS).
  • UVLO protection for both VDD and HB bias supplies with hysteresis to prevent chatter.
  • TTL and CMOS compatible inputs with enhanced noise immunity.
  • Low quiescent current and industry-standard SOIC-8 package.

Applications

  • Motor drive (stepper motors, HVAC, fans, power tools, robotics, drones).
  • Bridge converters in offline AC/DC power supplies.
  • High-density switch mode power supplies for server, telecom, IT, and industrial infrastructures.
  • DC-to-AC inverters.
