ISL78420 - Half-Bridge Driver

Description

DESCRIPTION Analog input supply voltage and positive supply for lower gate driver.

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 using multiphase PWM controllers (e. g. ISL78220/225/226).
On-chip 1Ω (dynamic) bootstrap diode.
10ns rise and fall times with 1000pF load.
8V to 14V operating voltage range.

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 Interleaved Boost PWM Controller” and the ISL78226 “6-Phase 12V/48V Bidirectional Synchronous PWM Controller”. It can also be used in applications where a standard half-bridge driver is needed.
