UC1710 UC2710 UC3710 High Current FET Driver FEATURES • Totem Pole Output with 6A Source/Sink Drive • 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 • MINIDIP and Power Packages DESCRIPTION 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 VIN and VC can independently range from 4.7V to 18V. These devices a [ ... ]
