Overview
UC1706 UC2706 UC3706 Dual Output Driver FEATURES • • • • • • • • • • • • • Dual, 1.
5A Totem Pole Outputs 40nsec Rise and Fall into 1000pF Parallel or Push-Pull Operation Single-Ended to Push-Pull Conversion High-Speed, Power MOSFET Compatible Low Cross-Conduction Current Spike Analog, Latched Shutdown Internal Deadband Inhibit Circuit Low Quiescent Current 5 to 40V Operation Thermal Shutdown Protection 16-Pin Dual-In-Line Package 20-Pin Surface Mount Package DESCRIPTION The UC1706 family of output drivers are made with a high-speed Schottky process to interface between low-level control functions and high-power switching devices - particularly power MOSFET's.
These devices implement three generalized functions as outlined below.
First: They accept a single-ended, low-current digital input of either polarity and process it to activate a pair of high-current, totem pole outputs which can source or sink up to 1.
5A each.
Second: They provide an optional single-ended to push-pull conversion through the use of an internal flip-flop driven by double-pulsesuppression logic.
With the flip-flop disabled, the outputs work in parallel for 3.
0A capability.
Third: Protection functions are also included for pulse-by-pulse current limiting, automatic deadband control, and thermal shutdown.
These devices are available in a two-watt plastic “bat-wing” DIP for operation over a 0°C to 70°C temperature range and, with reduced power, in a hermetically sealed cerdip for -55°C to +125°C operation.
Also available in surface mount Q and L packages.
