Overview
The ISO5500DWR, produced by Texas Instruments, is a 2.5 A isolated IGBT and MOSFET gate driver. This device is designed to drive IGBTs and MOSFETs with power ratings up to 150 A and 1200 V. It features a capacitive, silicon dioxide (SiO2) isolation barrier, which separates the input TTL logic and output power stage, ensuring high voltage isolation and preventing noise currents from interfering with sensitive circuitry.
The ISO5500DWR operates over a wide temperature range from –40°C to 125°C and is available in a 16-pin SOIC package. It includes various protection features such as over-current protection (DESAT), undervoltage lockout (UVLO), and fault feedback mechanisms.
