The FAN7171_F085 is a monolithic high-side gate drive IC, which can drive high-speed MOSFETs and IGBTs that operate up to +600V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The UVLO circuit prevents malfunction when VBS is lower than the specified threshold voltage. The high-current and low-output voltage drop feature makes this device suitable for sustained switch driver and energy recovery switch driver in the Plasma Display Panel application, motor drive inverter.
The FAN7171_F085 is a monolithic high-side gate drive IC designed to drive high-speed MOSFETs and IGBTs. It features a floating channel for bootstrap operation up to +600V and includes a common-mode dv/dt noise canceling circuit to ensure stable operation under high noise conditions. The device offers 4A sourcing and sinking current driving capability and is compatible with 3.3V and 5V input logic.
