FULLY INTEGRATED HOT-SWAP SOLUTION: MP5990
The MP5990 is the industry’s first fully integrated, 16V, 50A hot-swap solution with a PMBus interface. It is optimized for applications where protection against hot-plug functions is critical, including servers, PCIe cards, and 5G telecom and networking. The MP5990 integrates a hot-swap controller and power MOSFET with current and temperature sensing, plus an I2C/PMBus interface and a non-volatil...
ACCURATE CURRENT MEASUREMENT IN MODERN ELECTRONIC CIRCUITS
As power electronic switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, with each method having advantages and limitations. This article focuses on current measurement methods that require relatively high accuracy and bandwidth, such as those used to measure current on the inpu...
HIGHLY INTEGRATED, SCALABLE, CURRENT-SHARING HOT-SWAP SOLUTION FOR 48V DATACENTER APPLICATIONS
Servers and racks used in datacenters have undergone a considerable increase in power, going from a few hundred watts to multiple kilowatts. The distribution of these higher power levels on multiple servers inevitably generates greater power losses and hinders efficiency. This aspect can be mitigated by transiting from a traditional 12V distribution voltage to 48V. The increase in distribution vo...
SCALABLE CURRENT-SHARING E-FUSE SOLUTION
In typical hot-swap or electronic fuse (e-fuse) applications, great care must be taken when selecting the MOSFET to ensure that the safe operating area (SOA) of the device is not exceeded during a soft-start (SS) turn-on. Even if multiple MOSFETs are paralleled, the soft-start condition causes large amounts of thermal stress. Generally, when using discrete MOSFETs in hot-swap and e-fuse applicati...
