ISO5852SDWR Isolators - Gate Drivers by Texas Instruments

The ISO5852SDWR from Texas Instruments is a high-performance, reinforced digital isolator specifically designed for use in industrial applications. 5.7-kVRMS, reinforced isolated gate driver for IGBTs and MOSFETs with split outputs, OUTH and OUTL, providing 2.5-A source and 5-A sink current. The input side operates from a single 2.25-V to 5.5-V supply. The output side allows for a supply range from minimum 15 V to maximum 30 V. Two complementary CMOS inputs control the output state of the gate driver. The short propagation time of 76 ns provides accurate control of the output stage. With its reinforced insulation and high isolation voltage, this digital isolator ensures the safe transmission of data signals between different domains, safeguarding sensitive electronics from potential damage. 

Key Features:

• High Isolation Voltage: The ISO5852SDWR provides reinforced insulation and high isolation voltage, ensuring reliable signal isolation and protection against voltage transients.
• Robust EMC Performance: With low radiated emission and high immunity to electromagnetic interference (EMI), the isolator maintains signal integrity in noisy industrial environments.
• High-Speed Operation: Capable of high-speed data transmission up to several megabits per second (Mbps), enabling rapid communication between isolated systems without sacrificing performance.
• Wide Temperature Range: Designed to operate over a wide temperature range, from -40°C to +125°C, making it suitable for harsh industrial environments.
• Integrated Diagnostics: The device features built-in diagnostic functions, such as undervoltage lockout (UVLO) and overtemperature shutdown (OTSD), enhancing system reliability and safety.
• Low Power Consumption: Optimized for low power consumption, the ISO5852SDWR helps minimize energy consumption and prolongs battery life in battery-powered applications.
• Small Footprint: Available in small-footprint packages, such as the SOIC-8 package, the isolator offers space-saving benefits and facilitates easy integration into compact designs.
