Device Overview

Summary

The Micrel MIC4600 is a 28V half bridge MOSFET driver targeted for cost sensitive applications requiring high performance such as set-top boxes, gateways, routers, computing peripherals, telecom and networking equipment. The MIC4600 operates over a supply range of 4.5V to 28V. It has an internal linear regulator which provides a regulated 5V to power the MOSFET gate drive and operates up to 1.5MHz switching frequency. The MIC4600 uses an adjustable dead time circuit to prevent shoot-through in the external high and low-side MOSFETs. The MIC4600 is available in a small 3mm x 3mm QFN package with a junction temperature range of -40°C to 125°C.
