The integrated power MOSFET […]
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 […]
