FET Drivers are targeted for power supply applications.

Press Release Summary:



Suited for 24 and 48 V bus applications, Series MIC4100, 100 V drivers drive high and low side N-channel MOSFETS in half bridge and synchronous buck topologies. ICs are rated for 3 and 2 A sinking and sourcing peak currents and feature rise and fall times of 10 and 6 nsec combined with propagation delays of 24 nsec. They offer maximum supply voltage of 16 V, integrated bootstrap diode supporting maximum voltage of 118 V, and 3 nsec delay matching.

Micrel Launches New Family of 100V Half Bridge and Synchronous FET Drivers



SAN JOSE, Calif., Dec. 1 / - Micrel Inc. (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today rolled out a new family of 100V drivers designed to drive both high and low side N-channel MOSFETS in half bridge and synchronous buck topologies. These products are targeted for power supply applications in the server, networking, industrial, medical, automotive and avionic markets. The ICs are currently available in volume with pricing starting at $1.68 for 1,000 piece quantities.

"With voltages dropping and currents increasing, half-bridge and full- bridge configurations are quickly becoming the topology of choice in many applications," noted Ralf Muenster, Micrel's marketing director for power products. "Micrel's drivers are frequently used in these topologies and our MIC4100 family, with its improved performance and proven capability to reduce switching losses, is ideal for 24V and 48V bus applications."

The new family of ICs is rated for 3A and 2A sinking and sourcing peak currents and features rise and fall times as fast as 10 and 6ns combined with propagation delays of only 24ns. In addition, the devices offer a maximum supply voltage of 16V, an integrated bootstrap diode supporting a maximum voltage of 118V, a tight 3ns delay matching and UVLO protection. The MIC4100/01 feature dual independent inputs with symmetrical drivers while the MIC4103/4 support asymmetrical driving capabilities. The MIC4102 offers a simplified single input control with adaptive anti-shoot through technology optimizing switching transitions. All chips are sold in a compact SOIC-8 package option and come with a -40 to +125C junction temperature rating.
