DESCRIPTION

The UC1710 family of FET drivers is made with a high-speed Schottky pro-

cess to interface between low-level control functions and very high-power

switching devices-particularly power MOSFET’s. These devices accept

low-current digital inputs to activate a high-current, totem pole output which

can source or sink a minimum of 6A.

Supply voltages for both V

IN

and V

C

can independently range from 4.7V to

18V. These devices also feature under-voltage lockout with hysteresis.

The UC1710 is packaged in an 8-pin hermetically sealed dual in-line pack-

age for –55°C to +125°C operation. The UC2710 and UC3710 are speci-

fied for a temperature range of –40°C to +85°C and 0°C to +70°C

respectively and are available in either an 8-pin plastic dual in-line or a

5-pin, TO-220 package. Surface mount devices are also available.
