TC429

M Features High Peak Output Current: 6A Wide Input Supply Voltage Operating Range: - 7V to 18V High-Impedance CMOS Logic Input Logic Input Threshold Independent of Supply Voltage Low Supply Current: - With Logic ‘1’ Input – 5 mA max. - With Logic ‘0’ Input – 0.5 mA max. Output Voltage Swing Within 25 mV of Ground or V DD Short Delay Time: 75 nsec max Available in the Space-Saving 8-Pin SOIC Package. High Capacitive Load Drive Capability: - tRISE, tFALL = 35 nsec max with C LOAD = 2500 pF TC429 General Description The TC429 is a high-speed, single output, CMOS-level translator and driver. Designed specifically to drive highly capacitive power MOSFET gates, the TC429 features a 2.5Ω output impedance and 6A peak output current drive. A 2500 pF capacitive load will be driven to 18V in 25 nsec. The rapid switching times with large capacitive loads minimize MOSFET switching power losses. A TTL/CMOS input logic level is translated into an output voltage swing that equals the supply voltage and will swing to within 25 mV of ground or VDD. Input voltage swing may equal the supply voltage. Logic input current is under 10 µA, making direct interface to CMOS/bipolar switch-mode power supply controllers easy. Input “speed-up” capacitors are not required. The CMOS design minimizes quiescent power supply current. With a logic ‘1’ input, power supply current is 5 mA maximum and decreases to 0.5 mA for logic ‘0’ inputs. For dual output MOSFET drivers, see the TC426/ TC427/T...
