High Current FET Driver
FEATURES
DESCRIPTION
• Totem Pole Output with 6A
Source/Sink Drive
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.
• 3ns Delay
• 20ns Rise and Fall Time into 2.2nF
• 8ns Rise and Fall Time into 30nF
• 4.7V to 18V Operation
Supply voltages for both V and V can independently range from 4.7V to
IN
C
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.
• Inverting and Non-Inverting Outputs
• Under-Voltage Lockout with
Hysteresis
• Thermal Shutdown Protection
• MINIDIP and Power Packages
