Microchip TC428COA

Low-Side24,5 В ~ 18 В

Overview

The TC426/TC427/TC428COA 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/TC428COA 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 TC428COA contains an inverting and non-inverting driver.Other pin compatible driver families are the TC1426/27/28, TC4426/27/28, and TC4426A/27A/28A.
