High Current Logic Level MOSFET DriverNo. AN9301 April 1994 Application Note HIGH CURRENT LOGIC LEVEL MOSFET DRIVER Author: John Prentice Introduction Although the HV400 was designed as an interface between down resistor. The input voltage should be no more than 2V a pulse transformer and a power MOSFET, there are above pins 4 and 5 to make sure that Q1 will not turn back applications for high current MOSFET gate drive controlled on. by standard logic. This application note provides a method of D1 interfacing the HV400 to logic signals. It also reviews the PIN 7 ……
