October 29, 2024, Shanghai – NOVOSENSE Microelectronics, a semiconductor company specializing in high-performance analog and mixed-signal chips, has announced the NSM211x, a series of automotive-grade fully integrated high-bandwidth, high-isolation current sensors that both ensure precise current measurement and eliminate the need for any external isolation components.
On display at Electronica 2024 (Stand B5.450), the automotive-grade series targets applications including OBC/DC-DC converters, PTCs, automotive motor control, charging station current detection and fuel cell systems.
Certified to meet AEC-Q100 Grade 0 reliability standards, the series is designed to operate stably within a wide temperature range (-40 to 150°C) and addresses the needs of AC or DC current detection in automotive applications with a high isolation voltage, strong current handling capability and high reliability.
With a -3 dB bandwidth of up to 1 MHz and a response time of 400 ns, the NSM211x series helps control systems achieve rapid loop control and overcurrent protection. The series also features a creepage distance of up to 8.2mm and isolation voltage withstand of 5,000 Vrms per UL standards, with a maximum working isolation voltage of 1,618 Vpk.
It is available in three packaging options, SOP8, SOW16 and SOW10. These respectively have a primary side impedance of 1.2 mΩ, 0.85 mΩ/1 mΩ and an industry leading 0.27mΩ, with a continuous current handling capability of up to 100 A. Multiple product models are available for each package.
The current sensors integrate internal temperature compensation algorithms and offline calibration to enable a high measurement accuracy (<±2% sensitivity error and <±10 mV offset error) across the full temperature range, with no need for secondary programming.
The NSM211x series supports 3.3 V and 5 V power supply voltage as well as DC or AC current measurement with a current range of 5~200 A with options for reference voltage output, overcurrent protection output, and configurable overcurrent protection thresholds.
