FAN73901MX

The FAN73901MX is a monolithic high- and low-side Gate Drive IC for HID lamp ballast. It 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. High-voltage process and common-mode noise cancelling 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 VDD and VBS are lower than the specified threshold voltage.

• Floating channel for bootstrap operation to +600V
• Common-mode dv/dt noise cancelling circuit
• Built-in under-voltage lockout for both channels
• Matched propagation delay for both channels
• Output in-phase with input
