Product Overview
UCC27538 from Texas Instruments is a single-channel high-speed FET and IGBT gate driver in the Power_Management category. The UCC27538 variant uses dual TTL/CMOS-compatible non-inverting inputs, IN1 and IN2, and does not include an enable pin. Its output structure is split, with OUTH specified for 2.5-A peak source current and OUTL specified for 5-A peak sink current.
The driver operates from a recommended VDD range of 10 V to 35 V, with 35 V listed as the maximum VDD in the device comparison data. Timing parameters include 17 ns typical propagation delay, 15 ns typical rise time, and 7 ns typical fall time under a 1800-pF load condition.
The package is SOT-23-6 (DBV), with a 2.90 mm x 1.60 mm nominal body size. Pin assignments are VDD, IN1, GND, OUTL, IN2, and OUTH. Assembly and stress limits include 300°C lead temperature for 10 seconds, 260°C reflow temperature, ±4000 V HBM ESD rating, and ±1000 V CDM ESD rating.
