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.
Additional Features
Adjustable dead time circuitry
Anti-shoot-through protection
Internal LDO for single supply operation
Input voltage range: 4.5V to 28V
Fast propagation delay: 20ns
Up to 1.5 MHz operation
Low voltage logic level inputs for µC or FPGA driven power solutions
Independent inputs for low and high side drivers
2Ω gate drive capable of driving 3000pF load with 15ns rise and fall times
Low 450µA typical quiescent current
3mm x 3mm QFN package
-40°C to +125°C junction temperature range
