Half-Bridge Gate Driver
Features
Description
„ Floating Channels Designed for Bootstrap Operation
The FAN7382, a monolithic half-bridge gate driver IC,
can drive MOSFETs and IGBTs that operate up to
+600V. Fairchild’s high-voltage process and commonmode noise canceling technique provides stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level shift circuit allows high-side
gate driver operation up to VS=-9.8 V(typ.) for VBS=15V.
The input logic level is compatible with standard TTLseries logic gates. UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the
specified threshold voltage. Output drivers typically
source/sink 350mA/650mA, respectively, which is suitable for fluorescent lamp ballasts, PDP scan drivers,
motor controls, etc.

The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings.

when properly used in accordance with instructions for use
provided in the labeling, can be reasonably expected to
result in a significant injury of the user.
2.
A critical component in any component of a life support,
device, or system whose failure to perform can be
reasonably expected to cause the failure of the life
support device or system, or to affect its safety or
effectiveness.
