General Description
The 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 1.5 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 3mm × 3mm VQFN
package with a junction temperature range of –40°C to
125°C.
