UCC21521CDWR Galvanically Isolated Gate Drivers
5.7kVrms 4A/6A Dual-channel Isolated Gate Driver
Product Overview
The UCC21521 is an isolated dual-channel gate driver with 4-A source and 6-A sink peak current. It is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5-MHz with best-in-class propagation delay and pulse-width distortion.
Key Features
  • Universal: dual low-side, dual high-side or half-bridge driver
  • Operating temperature range: –40 to +125°C
  • Switching parameters: 19-ns typical propagation delay, 10-ns minimum pulse width, 5-ns maximum delay matching, 6-ns maximum pulse-width distortion
  • Common-mode transient immunity (CMTI) greater than 100 V/ns
  • Surge immunity up to 12.8 kV
  • Isolation barrier life >40 years
  • 4-A peak source, 6-A peak sink output
  • TTL and CMOS compatible inputs
  • 3-V to 18-V input VCCI range to interface with both digital and analog controllers
  • Up to 25-V VDD output drive supply with 5-V, 8-V, 12-V VDD UVLO options
  • Programmable overlap and dead time
  • Rejects input pulses and noise transients shorter than 5 ns
  • Fast enable for power sequencing
  • Wide body SOIC-16 (DW) package
  • Safety-related certifications: 8000-VPK reinforced isolation per DIN V VDE V0884-11:2017-01, 5700-VRMS Isolation for 1 minute per UL 1577, CSA certification per IEC standards, CQC certification per GB4943.1-2011
Applications
  1. Isolated converters in offline AC-to-DC power supplies
  2. Server, telecom, IT, and industrial infrastructures
  3. Motor drive and DC-to-AC solar inverters
  4. LED lighting
  5. Inductive heating
  6. Uninterruptible power supply (UPS)
Detailed Description
The input side is isolated from the two output drivers by a 5.7-kVRMS reinforced isolation barrier, with a minimum of 100-V/ns common-mode transient immunity (CMTI). Internal functional isolation between the two secondary-side drivers allows a working voltage of up to 1500 VDC.
Every driver can be configured as two low-side drivers, two high-side drivers, or a half-bridge driver with programmable dead time (DT). The EN pin pulled low shuts down both outputs simultaneously and allows for normal operation when left open or pulled high. As a fail-safe measure, primary-side logic failures force both outputs low.
The device accepts VDD supply voltages up to 25 V. A wide input VCCI range from 3 V to 18 V makes the driver suitable for interfacing with both analog and digital controllers. All the supply voltage pins have under voltage lock-out (UVLO) protection.
With all these advanced features, the UCC21521 enables high efficiency, high power density, and robustness in a wide variety of power applications.
