Vishay Adds Nine Smart Power Stages to its Siliconix SiC8xx Family
April 05, 2021
Vishay released nine 70 A, 80 A, and 100 A VRPower smart power stages. These power stages feature integrated current and temperature monitoring in the 5 mm x 6 mm PowerPAK MLP56-39 package.
The company’s Siliconix SiC8xx family of smart power stages was designed to reduce energy costs for data centers and high-performance computing, in addition to 5G mobile infrastructure telecom applications.
Per a company press release, the power stages combine power MOSFETs and an advanced driver IC. The devices' high energy efficiency is a result of their internal MOSFETs' state of the art TrenchFET® Gen IV technology, which delivers industry benchmark performance to significantly reduce switching and conduction losses. The SiC8xx smart power stages deliver peak efficiency above 93 % in various application conditions.
Traditionally, solutions that monitor power consumption use inductor DCR sensing, which offers accuracy of 7%. The SiC8xx family utilizes low side MOSFET sensing for accuracy of < 3 %.
Further, the family offers an input range of 4.5 V to 21 V and switching frequencies up to 2MHz. It also supports 3.3 V and 5 V PWM logic with tri-state for compatibility.
