Next-generation current sense amplifier features enhanced accuracy

Semtech Corporation’s new, high-performance current sense amplifier features low power consumption, high accuracy across input voltages and simplified implementation for design engineers. This product extends their portfolio of current sense amplifiers with high-performance functionality for a wide range of analog applications. The current sense amplifier’s voltage is flexible—supporting 4V to 42V optimizing the device for use in a wide range of applications, such as battery chargers, notebook computers, telecommunications equipment, and wireless chargers. It is currently used on the company’s wireless charging reference designs. “Our new current sense amplifier reinforces Semtech’s portfolio of high-performance, low-power products that enable end-user applications of varying sizes and power requirements,” said Francois Ricodeau, product line manager for Semtech’s Power and High Reliability Products Group. “This system allows design engineers more design flexibility and simplified implementation due to its enhanced configuration.” The current sense amplifier is available in an eight-pin, SOT-23 package, and it is lead-free, halogen-free and RoHS/WEEE compliant.
