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.

INPUT

A OR B

6 k

INPUT

A OR B

5.6 V

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.

GND

UDG--00068

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
