Microchip Technology, Inc. 1.5A Dual Inverting High-Speed MOSFET Driver TC426

Description
The TC426/TC427/TC428 are dual CMOS high-speed drivers. A TTL/CMOS input voltage level is translated 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 make the TC426/TC427/TC428 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 1A, 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 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. The inverting TC426 driver is pin-compatible with the bipolar DS0026 and MMH0026 devices. The TC427 is noninverting; the TC428 contains an inverting and non-inverting driver. Other pin compatible driver families are the TC1426/27/28, TC4426/27/28, and TC4426A/27A/28A. For product comparison, please consider: TC4426A Additional Features High-Speed Switching (CL = 1000pF): 30nsec High Peak Output Current: 1.5A High Output Voltage Swing: VDD – 25mV GND +25mV Low Input Current (Logic "0" or "1"): 1mA TTL/CMOS Input Compatible Available in Inverting and Noninverting Configurations Wide Operating Supply Voltage: 4.5V to 18V Current Consumption Inputs Low: 0.4mA Inputs High: 8mA Single Supply Operation Low Output Impedance: 6Ω Pinout Equivalent of DS0026 and MMH0026 Latch-Up Resistant: Withstands > 500mA Reverse Current ESD Protected: 2kV

The TC426 is an 8-pin inverting dual high-speed MOSFET driver designed for switching mode power supplies, pulse transformer drive, and DC-to-DC converter applications. It operates from a 4.5V to 18V single supply and delivers 1.5A peak output current with a low output impedance of 6Ω. The device supports TTL/CMOS logic inputs with a maximum input current of 1 μA and switches a 1000 pF load 18V in 30 ns at 25°C. Output voltage swing is within 25 mV of the supply rails. It is available in 8-pin PDIP, SOIC, and CERDIP packages and is latch-up resistant with ESD protection rated at 2 kV. The device consumes 0.4 mA quiescent current with logic '0' inputs and 8 mA maximum with logic '1' inputs.
