description
The UC3709 family of power drivers is an
effective low-cost solution to the problem of
providing fast turn-on and off for the
capacitive gates of power MOSFETs. Made
with a high-speed Schottky process, these
devices will provide up to 1.5 A of either
source or sink current from a totem--pole
output stage configured for minimal
cross-conduction current spike.
The UC3709 is pin compatible with the
MMH0026 or DS0026, and while the delay
times are longer, the supply current is much
less than these older devices.
With inverting logic, these units feature complete TTL compatibility at the inputs with an output stage that can
swing over 30 V. This design also includes thermal shutdown protection.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All currents are positive into and negative out of the specified terminals. Digital drive can exceed 5.5V if input is limited to 10A. Consult the
Packaging Section of the Databook for thermal limitations and considerations of the package.
