UC3706 Dual Output Driver
FEATURES DESCRIPTION Dual, 1.5A Totem Pole Outputs 40nsec Rise and Fall into 1000pF Parallel or Push-Pull Operation 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. 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 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 -55В°C to +125В°C operation. Also available in surface mount Q and L packages. 20-Pin Surface Mount Package TRUTH TABLE 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. INV
