Dual-channel low-side 4/5-A gate driver ICs handle fast MOSFET, WBG switches
Infineon Technologies AG has released the new EiceDRIVER 2EDN product family. Aiming at space-limited designs, the next-generation devices complement the existing 2EDN driver ICs by providing higher system-level efficiencies, excellent power density, and consistent system robustness with fewer external components. Building upon this expansion, the 2EDN family is now able to drive the power switch […]
Four-terminal shunts provide precision current sensing
Low resistance values are important for high-efficiency current sensing because lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values accurately becomes challenging because of lead resistance errors. Using a four-terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation. The HCSK1216 provides […]
