Description

Niveau: Supérieur, Doctorat, Bac+8
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 de- vices implement three generalized functions as outlined below. First: They accept a single-ended, low-current digital input of either polar- ity 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-pulse- suppression 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.

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 de vices implement three generalized functions as outlined below. First: They accept a singleended, lowcurrent digital input of either polar ity 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pulse suppression 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 op eration 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 avail able in surface mount Q and L packages.
