onsemi FAN7393AMX

FAN7393A is a half-bridge gate driver IC with shutdown and programmable dead-time control, capable of driving high-speed MOSFETs and IGBTs operating at voltages up to +600V. It features a buffered output stage, with all NMOS transistors designed for high pulse current drive capability and minimum cross-conduction.

Fairchild's high-voltage process and common-mode noise cancellation technology enable the high-side driver to operate reliably in high dv/dt noise environments. The advanced level-shift circuit allows the high-side gate driver to operate with VS reaching -9.8V (typical) at VBS = 15V.

The UVLO circuit prevents malfunction when VDD and VBS fall below the specified threshold voltages.

The high-current and low output voltage drop characteristics make this device suitable for various applications including half-bridge and full-bridge inverters, motor drive variable frequency drives, switching power supplies, induction heating, and high-power DC-DC converters.
