UC1708 UC2708 UC3708 Dual Non-Inverting Power Driver FEATURES 3.0A Peak Current Totem Pole Output 5 to 35V Operation 25ns Rise and Fall Times 25ns Propagation Delays Thermal Shutdown and UnderVoltage Protection High-Speed, Power MOSFET Compatible Efficient High Frequency Operation Low Cross-Conduction Current Spike Enable and Shutdown Functions Wide Input Voltage Range ESD Protection to 2kV DESCRIPTION The UC1708 family of power drivers is made with a high-speed, highvoltage, Schottky process to interface control functions and high-power switching devices – particularly power MOSFETs. Operating over a 5 to 35 volt supply range, these devices contain two independent channels. The A and B inputs are compatible with TTL and CMOS logic families, but can withstand input voltages as high as VIN. Each output can source or sink up to 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 high signal at the Shutdown terminal or by forcing the Enable terminal low. The Shutdown 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 device in 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-voltag...
