The UC1710 family of FET drivers is made with a high-speed Schottky process 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
and VCcan independently range from 4.7V to
IN
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 specified 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.
