TC429 6A Single High-Speed, CMOS Power MOSFET Driver Features General Description High Peak Output Current: 6A The TC429 is a high-speed, single output, CMOS-level translator and driver. Designed specifically to drive Wide Input Supply Voltage Operating Range: highly capacitive power MOSFET gates, the TC429 - 7V to 18V features a 2.5 output impedance and 6A peak output High-Impedance CMOS Logic Input current drive. Logic Input Threshold Independent of Supply A 2500 pF capacitive load will be driven to 18V in Voltage 25 nsec. The rapid switching times with large Low Supply Current: capacitive loads minimize MOSFET switching power - With Logic 1 Input 5 mA max. losses. - With Logic 0 Input 0.5 mA max. A TTL/CMOS input logic level is translated into an Output Voltage Swing Within 25 mV of Ground output voltage swing that equals the supply voltage and or V DD . Input volt- will swing to within 25 mV of ground or V DD Short Delay Time: 75 nsec max age swing may equal the supply voltage. Logic input current is under 10 A, making direct interface to Available in the Space-Saving 8-Pin SOIC CMOS/bipolar switch-mode power supply controllers Package. easy. Input speed-up capacitors are not required. High Capacitive Load Drive Capability: -t , t = 35 nsec max with The CMOS design minimizes quiescent power supply RISE FALL current. With a logic 1 input, power supply current is C = 2500 pF LOAD 5 mA maximum and decreases to 0.5 mA for logic 0 Applications inputs.
