The TC428 is a dual complementary high-speed MOSFET driver from Microchip Technology, Inc., capable of delivering a peak output current of 1.5A. It features high-speed switching times of 30 nanoseconds for a 1000 pF load and operates within a supply voltage range of 4.5V to 18V. The device is designed for low input current, drawing only 1 ¬µA, and is compatible with TTL/CMOS logic levels. The TC428 supports both inverting and non-inverting configurations, making it versatile for various applications, including switch mode power supplies and pulse transformer drives. It has a low output impedance of 6Oc and is latch-up resistant, withstanding reverse currents greater than 500 mA. Additionally, the TC428 is ESD protected up to 2 kV, enhancing its reliability in demanding environments. The device is available in multiple package types, including 8-pin SOIC, PDIP, and CERDIP, with temperature ranges from 0¬8C to +70¬8C up to -55¬8C to +125¬8C, catering to a wide array of application needs.
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.
