FAN7888 — 3 Half-Bridge Gate-Drive IC
Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. T

=25°C, unless otherwise specified.
Notes:
1. Mounted on 76.2 x 114.3 x 1.6 mm PCB (FR-4 glass epoxy material).
2. 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.
3. Do not exceed P
D
under any circumstances.
Recommended Operating Conditions
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.
