UCC21225A

SLUSCV6A –APRIL 2017–REVISED FEBRUARY 2018

UCC21225A 4-A, 6-A, 2.5-kV Isolated Dual-Channel Gate Driver in LGA

RMS

1 Features

3 Description

The UCC21225A is an isolated dual-channel gate

driver with 4-A source and 6-A sink peak current in a

5-mm x 5-mm LGA-13 package. It is designed to

drive power transistors up to 5-MHz with best-in-class

propagation delay and pulse-width distortion.

•

Universal: Dual Low-Side, Dual High-Side or Half-

Bridge Driver

•

5 x 5 mm, Space-Saving LGA-13 Package

Switching Parameters:

–

19-ns Typical Propagation Delay

5-ns Maximum Delay Matching

6-ns Maximum Pulse-Width Distortion

The input side is isolated from the two output drivers

a 2.5-kV_RMSisolation barrier, with 100-V/ns

minimum common-mode transient immunity (CMTI).

Internal functional isolation between the two

secondary side drivers allows working voltage up to

•

CMTI Greater than 100-V/ns

4-A Peak Source, 6-A Peak Sink Output

TTL and CMOS Compatible Inputs

3-V to 18-V Input VCCI Range

700-V_DC

This driver can be configured as two low-side, two

high-side, or a half-bridge driver with programmable

dead time (DT). A disable pin shuts down both

outputs simultaneously when it is set high, and allows

normal operation when left open or grounded.

Up to 25-V VDD with 5-V UVLO

Programmable Overlap and Dead Time

Rejects Input Transients Shorter than 5-ns

Fast Disable for Power Sequencing

Safety-Related Certifications:

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.

3535-V_PKIsolation per DIN V VDE V 0884-

11:2017-01

With all these advanced features, the UCC21225A

enables high power density, high efficiency, and

robustness in a wide variety of power applications.
