SiC mosfets switch 60A at 225 deg C

Cissoid has used silicon carbide (SiC) mosfets in a power module which can operate reliably between -55°C and +225°C, delivering up to 60A.

With dual mosfets the module, called CHT-Pluto, is designed for for half-bridges with 30A continuous capability for both low-side and high-side…

Design ideas: Some practical ways to split a voltage rail

There are a number of reasons why an engineer would want to “split” a voltage rail in their design. Sometimes parts of the circuit, like a sensor or an IC, require a bipolar supply.

Other reasons are to make the best use of the dynamic range of your ADC if…
