TC426CPA General Description

The TC426/TC427/TC428 are dual CMOS high-speed gate drivers. A TTL/CMOS input voltage level is translated into a rail-to-rail output voltage level swing. The CMOS output is within 25 mV of ground or positive supply. The low impedance, high-current gate driver outputs swing a 1,000 pF load 18 V in 30 ns. The unique current and voltage drive qualities make the TC426/TC427/TC428 ideal power MOSFET gate drivers, line drivers, and DC-to-DC converter building blocks. Input logic signals may equal the power supply voltage. Low input current 1 µA, making direct interface to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analog comparators. Quiescent power supply current is 8 mA maximum. The TC426 requires 1/5 the current of the pin-compatible bipolar DS0026 device. This is important in DC-to-DC converter applications with power efficiency constraints and high-frequency switch-mode power supply applications. Quiescent current is typically 6 mA when driving a 1,000 pF load 18 V at 100 kHz.
