General Description
The MIC4600 is a 28V half-bridge MOSFET driver targeted for cost-sensitive applications that require 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 that provides a regulated 5V to power the MOSFET gate drive and operates up to 1.5 MHz 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 3 mm x 3 mm VQFN package with a junction temperature range of –40°C to +125°C.
