1 / 5 page UC1709, UC2709, UC3709 DUAL HIGH- SPEED FET DRIVER SLUS196A -- NOVEMBER 1996 -- REVISED MARCH 2000 1 POST OFFICE BOX 655303 · DALLAS, TEXAS 75265 D 1.5 Amp Source/Sink Drive D Pin Compatible with 0026 Products D 40 ns Rise and Fall into 1000pF D Low Quiescent Current D 5 V to 40 V Operation D Thermal Protection 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. absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†}}}} N--Pkg J--Pkg Supply Voltage, VCC 40 V 40V ........................................... .......................

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.
