3A Dual High-Speed Power MOSFET Drivers

TC4423A The TC4423 TC4424 TC4425 devices are a family of 3A, dual-output Buffers MOSFET drivers. Pin compati- ble with the TC1426 27/28, TC4426 27/28 and TC4426A 27A/28A dual 1.5A driver families, the TC4423 24/25 family has an increased latch-up current rating of 1.5A, making them even more robust for operation in harsh electrical environments. As MOSFET drivers, the TC4423 TC4424 TC4425 CAN easily charge 1800 pF Gate capacitance in under 35 nsec, providing low enough impedances in both the on and off states to ensure the MOSFET's intended state will not be affected, even by large transients. The TC4423 TC4424 TC4425 inputs may be driven directly from either TTL or CMOS (2.4V to 18V). In addition, the 300 mV of built-in hysteresis provides noise immunity and allows the device to be driven from slowly rising or falling waveforms. By Microchip Technology Inc.
