Southchip officially launched its full series of integrated current sensors, SCS81XX. The series is available in three package options, each achieving industry-leading performance in key specifications such as temperature drift accuracy, bandwidth, and current sensing range. This new product precisely addresses the demands for high precision, high efficiency, low power consumption, and miniaturization in core application scenarios including digital energy, new energy vehicles, server power supplies, and industrial automation, driving the advancement of next-generation industrial platforms.

SCS81XX series leverages a closed-loop architecture combined with a CFC correction algorithm and integrates Southchip's proprietary Hall process technology. It surpasses industry standards across several key technical metrics:

Extreme Temperature Drift Control: Based on Southchip's proprietary CFC correction algorithm, SCS81XX series achieves a sensitivity temperature drift of 1% and a VOE full-temperature drift of ±1mV. This comprehensively outperforms the common industry standards of 2% sensitivity drift and ±10mV VOE drifts. This exceptional low-drift characteristic enables direct replacement of bulkier current sensor modules on the AC side of PV inverters, significantly reducing both board area and system cost. On the PV side, it facilitates more accurate Maximum Power Point Tracking (MPPT), thereby enhancing the overall conversion efficiency of the inverter.

High Bandwidth: SCS81XX series supports a maximum bandwidth of up to 2MHz, allowing it to faithfully reproduce high-speed inductor current waveforms in SiC-based platforms without distortion. With a response time of ≤0.3μs, it meets the demands for precise current detection at high switching frequencies.

Ultra-Low Impedance: Through an innovative low-impedance frame design, SCS81XX achieves a primary conductor impedance as low as 0.2mΩ. This significantly reduces conduction losses, enhances the device's own heat dissipation capability, and extends the current sensing range. The maximum peak detectable current reaches 250A. In practical tests at an ambient temperature of 85℃ with a continuous current of 60Arms, the chip temperature rise is ≤25℃

High Surge Current Withstand Capability: Digital energy equipment often operates under harsh conditions such as lightning strikes and inrush currents during switching. SCS81XX series is engineered for robustness, featuring a high surge current withstand capability of up to 25kA, a surge voltage tolerance of 11kV, and a VCC pin withstand voltage of 12V, providing reliable protection for safe equipment operation.

SCS81XX series offers both high-precision and cost-effective options. It is available in three packages – SOW10, SOW16, and SOP8 – and supports three current sensing ranges: 20A-250A, 10A-150A, and 10A-60A. This board coverage and granular segmentation allow for flexible adaptation to various power level requirements within digital energy systems.
