MIC4600 28V Half-Bridge MOSFET Driver Features General Description Adjustable Dead Time Circuitry The MIC4600 is a 28V half bridge MOSFET driver targeted for cost sensitive applications requiring high Anti-Shoot-Through Protection performance such as set-top boxes, gateways, routers, Internal LDO For Single Supply Operation computing peripherals, telecom and networking Input Voltage Range: 4.5V to 28V equipment. Fast Propagation Delay 20 ns The MIC4600 operates over a supply range of 4.5V to Up To 1.5 MHz Operation 28V. It has an internal linear regulator which provides a Low Voltage Logic Level Inputs For C or FPGA regulated 5V to power the MOSFET gate drive and Driven Power Solutions operates up to 1.5 MHz switching frequency. Independent Inputs For Low and High Side The MIC4600 uses an adjustable dead time circuit to Drivers prevent shoot-through in the external high and low-side 2 Gate Drive Capable Of Driving 3000 pF Load MOSFETs. With 15 ns Rise and Fall Times The MIC4600 is available in a small 3mm 3mm VQFN Low 450 A Typical Quiescent Current package with a junction temperature range of 40C to 3 mm 3 mm VQFN Package 125C. 40C to +125 C Junction Temperature Range Package Types Applications Distributed Power Systems MIC4600 Communications/Networking Infrastructure 3x3 VQFN Set-Top Box, Gateways And Routers Top View Printers and Scanners P and FPGA Controlled DC-DC Regulator 16 15 14 13 1 12 DH VIN 2 11 SW EN EPAD 3 10 HSI DL 4 LSI 9 PGND 56 78 2016 Microchip Technology Inc.
