FAN73932
Half-Bridge Gate Drive IC
Features
Description
Floating Channel for Bootstrap Operation to +600V
The FAN73932 is a half-bridge, gate-drive IC with shutdown and dead-time functions which can drive highspeed 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.
Typically 2.0A/2.0A Sourcing/Sinking Current Driving
Capability
Extended Allowable Negative VS Swing to -9.8V for
Signal Propagation at VBS=15V
High-Side Output in Phase of IN Input Signal
3.3V and 5V Input Logic Compatible
Matched Propagation Delay for Both Channels
Cycle-by-Cycle Edge-Triggered Shutdown Function
Built-in UVLO Functions for Both Channels
Built-in Common-Mode dv/dt Noise Canceling Circuit
Internal 400ns Minimum Dead-Time
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 VDD and
VBS are lower than the specified threshold voltage.
Applications
High-Speed Power MOSFET and IGBT Gate Driver
Induction Heating
The high-current and low-output voltage drop feature
makes this device suitable for all kinds of half- and fullbridge inverters, like motor drive inverter, switching
mode power supply, induction heating, and high-power
DC-DC converter applications.
High-Power DC-DC Converter
