DATASHEET ISL78420 100V, 2A Peak, Half-Bridge Driver with Tri-Level PWM Input and Adjustable Dead-Time FN8296 Rev 4.00 September 29, 2016 The ISL78420 is a 100V, 2A high frequency half-bridge NMOS FET driver with a tri-level PWM input.

With an operating supply range of 8V to 14V and integrated high-side bootstrap bias, it supports driving the high-side and low-side NMOS in 100V halfbridge applications.

This driver is designed to work in conjunction with the ISL78220 and ISL78225 “Multi-Phase

ISL78420 Features

* 114VDC bootstrap supply maximum voltage

* 2A source and sink driver for 100V half-bridge NMOS FETs

* Programmable dead-time prevents shoot-through; adjustable from 35ns to 220ns with a single resistor

* Unique tri-level PWM input logic enables phase shedding when us
