Product Overview

The UCC27531 is a Texas Instruments single-channel high-speed gate driver for MOSFET and IGBT power switches. It provides a single non-inverting input and supports TTL and CMOS compatible input logic with thresholds independent of supply voltage. Device variants support enable function availability as Yes/No and output configuration as Split/Single.

The driver operates from a recommended VDD range of 10 V to 35 V, with 35 V maximum VDD identified for the UCC27531. At 18 V VDD, the driver provides 2.5 A peak source current and 5 A peak sink current. Timing parameters include 17 ns typical propagation delay, 15 ns typical rise time, and 7 ns typical fall time with a 1800 pF load.

Package options include SOT-23-6 DBV at 2.90 mm x 1.60 mm and SOIC-8 D at 4.90 mm x 3.91 mm. Assembly and limit data include 300°C lead temperature for 10 seconds, 260°C reflow temperature, -65°C to 150°C storage temperature, ±4000 V HBM ESD rating, and ±1000 V CDM ESD rating.
