Enhanced isolated gate driver ICs offer multiple protection features

05-03-2021 | Mouser Electronics | Semiconductors

Infineon Technologies EiceDRIVER Enhanced Isolated Gate Driver ICs, available now from Mouser, offer protection features including DESAT, miller clamp, soft-off for MOSFETs, IGBTs, and SiC MOSFETs. The miller clamp and accurate short-circuit protection (DESAT) facilitates superior application safety by avoiding parasitic turn-on and short-circuit when driving CoolSiC SiC MOSFET and TRENCHSTOP IGBT7. These single-channel and dual-channel gate driver ICs are offered as X3 analog family (1ED34xx) and X3 digital family gate driver ICs. The 1ED34xx and 1ED38xx gate driver ICs provide 9A output current and 40Vmax output voltage in a space-saving DS0-16 fine pitch wide-body package with 8mm creepage.

These ICs feature short-circuit clamping and active shutdown and give the highest isolation capability used in the 1500V DC solar inverter application.

The X3 analog and digital gate driver ICs are UL 1577 certified 5.7kV(RMS) VISO for 1min and VDE 0884-11 certified reinforced isolation 1767V VIORM.

Typical applications include solar string inverters, EV charging, UPS, industrial drives, CAC, welding equipment, induction heating appliances, and power supplies for server and telecommunication systems.
