MICROCHIP TC426CPA

The TC426CPA is a dual inverting high-speed Power MOSFET Driver can translate TTL/CMOS input voltage level into a rail-to-rail output voltage level swing. The CMOS output is within 25mV of ground or positive supply. The low-impedance, high-current driver outputs swing a 1000pF load 18V in 30nsec. The unique current and voltage drive qualities makes the TC426 ideal power MOSFET drivers, line drivers and DC-to-DC converter building blocks. Input logic signals may equal the power supply voltage. Input current is a low 1 uA, making direct interface input current is a low 1 to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analogue comparators. Quiescent power supply current is 8mA 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 6mA when driving a 1000pF load 18V at 100kHz.
