The FAN73832 is a half-bridge, gate-drive IC with shut-down and programmable dead-time control functions for driving MOSFETs and IGBTs, operating up to +600V. Fairchild’s high-voltage process and common-mode noise canceling technique provide stable operation of high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The UVLO circuits for both channels prevent malfunction when VDD and VBS are lower than the specified thresh- old voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for all kinds of half- and full-bridge inverters.
The FAN73832 is a half-bridge gate-drive IC designed for driving MOSFETs and IGBTs in applications such as SMPS, motor drive inverters, and fluorescent lamp ballasts. It operates up to +600V and includes features like floating channel bootstrap operation, built-in UVLO functions, and a common-mode dv/dt noise canceling circuit to ensure stable high-side driver operation.
The device offers typically 350mA sourcing and 650mA sinking current capability for both channels. It features an internal 400ns minimum dead-time and programmable turn-on delay-time control. The IC is available in 8-SOP and 8-DIP packages with an operating temperature range of -40°C to 125°C.
