AEC-Q100 Single-Input, Dual-Output Isolated Gate Driver with 4A Source and 6A Sink

June 19, 2019 by Scott McMahan

The UCC20225-Q1 from Texas Instruments (TI) is a single-input, dual-output isolated gate driver with 4A source and 6A sink peak current in 5mm x 5mm LGA-13 package. TI designed UCC20225-Q1 to drive power transistors up to 5MHz with what TI describes as best-in-class propagation delay and pulse-width distortion.

The input side is isolated from the two output drivers by a 2.5kVrms isolation barrier, with minimum 100V/ns common-mode transient immunity (CMTI).

Internal, functional isolation between the two output-side drivers allows working voltage up to 700Vdc. The device's dead time (DT) is programmable through a resistor on the DT pin. When it is set high, a disable pin shuts down both outputs simultaneously. It also allows regular operation when left open or grounded.

VDD supply voltages up to 25V are accepted. A wide VCCI range from 3V to 18V makes the driver suitable for interfacing with both analog and digital controllers. All supply voltage pins feature under-voltage lock-out (UVLO) protection.

TI says that the UCC20225-Q1 enables high power density, high efficiency, and robustness in a variety of automotive applications.
