The ISO5852S is a 5.7-kVRMS, reinforced isolated, IGBT gate driver with split outputs, OUTH and OUTL, providing 2.5-A source and 5-A sink currents. The primary side operates from a single 3-V or 5-V supply.
Insulated gate bipolar transistors (IGBTs) are gaining considerable use in circuits requiring high voltage and current at moderate switching frequencies up to 100 kHz. Typically these circuits are in motor drive,
• Isolated power supply supporting six IGBT gate drivers of the three-phase inverter • Quasi-resonant boundary conduction mode along with frequency modulation provides peak efficiency of 90% at balanced full load • Supplies output power up to 1.2 W per IGBT driver • Provides compact and cost-effective solution due to
The UCC27524A is a dual-channel gate driver originally designed to drive capacitive loads in the form of MOSFETs and IGBTs. The device is capable of sourcing and sinking up to 5A peak for short periods.
After DESAT detection, gate drivers (including ISO5x5x and UCC217xx families) will immediately begin pulling the gate low to turn off the IGBT and end the short circuit condition. Gate drivers with DESAT protection have a built-in threshold which is effective for many IGBTs, but could be slightly too high or too low for other IGBTs or other ...
This reference design details a gate driver circuit for a three-phase inverter. The gate drive circuit comprises of three UCC21520 devices, which are dual IGBT gate drivers. The UCC21520 has many features to design a reliable three phase inverter.
