UC1710 UC2710 UC3710 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 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. • 3ns Delay • 20ns Rise and Fall Time into 2.2nF • 8ns Rise and Fall Time into 30nF • 4.7V to 18V Operation • Inverting and Non-Inverting Outputs • Under-Voltage Lockout with Hysteresis • Thermal Shutdown Protection Supply voltages for both VIN and VC 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 package 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. • MINIDIP and Power Packages ORDERING INFORMATION TRUTH TABLE INV N.I. Out H H L OUT= INV and N.I. L H H OUT= INV or N.I.
