In the rapidly evolving landscape of semiconductor technology, the demand for precise current sensing and efficient control solutions
has become
increasingly prominent. Shanghai Analogy Semiconductor Technology Co., Ltd. (hereinafter referred to as "Analogysemi") leverages
its strong foundation in analog and mixed-signal chip design to proudly unveil its new high-performance solution for the field of precision current measurement and control—the CSA52x series current sense amplifiers.
This series of chips aims to bring unprecedented accuracy and efficiency to high-side and lowside current sensing applications, covering a wide range of fields including power tools, communication power supplies,
electronic vaporizers, and PoE.
The CSA52x series chips offer a broad supply voltage range (2.7V to 5.5V) and a common-mode voltage input range (-0.3V to 36V), combined with six fixed gain options (20V/V, 25V/V, 50V/V, 75V/V, 100V/V, and 200V/V),
providing great flexibility and precision for system design.
Notably, the CSA521x model supports bidirectional current sensing through the REF pin,
achieving a bandwidth of up to 350kHz and a slew rate of 0.8V/us at a gain setting of 20V/V.
In terms of precision, the CSA52x series demonstrates exceptional performance,
with a typical offset voltage of ±15uV, temperature drift of only 0.05uV/°C, and gain error across the full temperature range at 0.2%, with a typical temperature drift of 3ppm/°C to 10ppm/°C. Its pin design is compatible with various application scenarios, including power tools, electronic vaporizers,
communication power supplies, Power-over-Ethernet (PoE), and other areas requiring high-side or low-side current sensing.
