FEATURES● 3.0A Peak Current Totem PoleOutput● 5 to 35V operation● 25ns Rise and Fall Times● 25ns Propagation Delays● Thermal Shutdown and Under-Voltage Protection● High-Speed, Power MOSFETCompatible● Efficient High Frequency Operation● Low Cross-Conduction CurrentSpike● Enable and Shutdown Functions● Wide Input Voltage Range● ESDProtection to 2kVDESCRIPTIONThe UC1708 family of power drivers is made with a high-speed,high-voltage, Schottky process to interface control functions and high-powerswitching devices - particularly power MOSFETs.Operating over a 5 to 35volt supply range,these devices contain two independent channels.The Aand B inputs are compatible with TTL and CMOSlogic families,but canwithstand input voltages as high as VIN.Each output can source or sink upto 3A as long as power dissipation limits are not exceeded.Although each output can be activated independently with its own inputs,they can be forced low in common through the action of either a digital highsignal at the Shutdown terminal or by forcing the Enable terminal low.TheShutdown terminal will only force the outputs low, it will not effect the behavior of the rest of the device.The Enable terminal effectively places the devicein under-voltage lockout, reducing power consumption by as much as 90%.During under-voltage and disable (Enable terminal forced low) conditions,the outputs are held in a self-biasing,low-voltage, state.The UC3708 and UC2708 are available in plastic 8-pin MINI DIP and 16-pin“bat-wing DIP packages for commercial operation over a 0℃to +70℃temperature range and industrial temperature range of -25℃to +85℃respectively. For operation over a -55℃to +125℃temperature range,theUC1708 is available in hermetically sealed 8-pin MINICDIP,16 pin CDIPand 20 pin CLCC packages.Surface mount devices are also available.
