Description
The FAN7380 is a monolithic half-bridge gate drive IC for
MOSFETs and IGBTs, which operate up to +600V.
Fairchild’s high-voltage process and common-mode
noise canceling technique give 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
input logic level is compatible with standard TTL-series
logic gates. The internal shoot-through protection circuit
provides 100ns dead-time to prevent output switching
devices from both conduction during transition periods.
UVLO circuits for both channels prevent malfunction
when VCC and VBS are lower than the specified
threshold voltage. Output drivers typically source/sink at
90mA/180mA, respectively, which is suitable for
fluorescent / compact fluorescent lamp ballast
applications and the systems that require low di/dt noise.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In
addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only. TA=25°C, unless otherwise specified.
Notes:
2. Mounted on 76.2 x 114.3 x 1.6mm PCB (FR-4 glass epoxy material).
3. Refer to the following standards:
JESD51-2: Integral circuits thermal test method environmental conditions - natural convection
JESD51-3: Low effective thermal conductivity test board for leaded surface mount packages
4. Do not exceed PD under any circumstances.
Recommended Operating Ratings
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
