New at Mouser: Allegro's Coreless ACS37610 Hall-Effect Current Sensor IC with Superior SNR for EVs and Industrial Use

April 2, 2024 – Mouser Electronics, Inc., the authorized global distributor with the newest electronic components and industrial automation products, is now stocking the ACS37610 current sensor IC from Allegro MicroSystems. Touted as the industry's first family of Hall-Effect-sensing solutions targeted at automotive and industrial systems, the ACS37610 offers a genuinely coreless solution designed to measure currents from 100A to greater than 4,000A flowing through a busbar or PCB trace without the need for an external concentrator or U-shaped magnetic shield.

Allegro MicroSystems ACS37610 Current Sensor IC, available from Mouser Electronics, is AEC-Q100 Grade 0 automotive qualified and is well suited for EV high-voltage traction motor inverters, 48V/12V auxiliary inverters, overcurrent detection, DC/DC converters, heterogeneous redundant battery monitoring, smart fuses, power distribution units (PDUs) and power supplies. It enables engineers to accurately measure hundreds or thousands of amps in a very economical and straightforward way and provides excellent immunity, greater precision, higher power density and enhanced efficiency while reducing system complexity, non-linearity errors, BOM cost, footprint and weight.

The ACS37610 delivers a high accuracy of 1% (typ.), a speedy response time of <2 μs (typ.) and offers factory-programmed segmented linear temperature compensation (TC) to provide low thermal drift. The IC features innovative differential Hall-based sensing technology, resulting in a 2.5x improvement in signal-to-noise ratio (SNR) with 2x lower noise compared to previous generations. The lower noise brings superior resolution for accurate torque control, while the sensor's 4x higher sensitivity range provides for more flexible busbar and PCB designs. To further improve the system's SNR, the ACS37610 also features larger Hall element spacing to accommodate notching to the current-carrying busbar or PCB copper trace. While not mandatory, this notching results in virtually no hotspots or thermal performance degradation.

High isolation and reliability are achieved through the no-contact nature of the simplified assembly and the IC's DC to 250 kHz high-operating sensor bandwidth, resulting in contactless, lossless and non-invasive current sensing. Combine that with a dedicated user-programmable overcurrent (OCF) and overtemperature (OTF) fault pin and a slew of built-in diagnostics, and the ACS37610 is ideal for safety-critical applications. Additional accuracy and flexibility of the ACS37610 are enhanced by user programmability, performed via the output pin or the dedicated programming pin. It comes in an ultra-compact, surface mountable, low-profile 8-pin TSSOP8 package. The device is offered in 150 kHz and 250 kHz bandwidth options, as well as regular and low-power modes, and has an ambient temperature range of -40°C to 150°C. The device is supported by the ASEK37610 evaluation boards, also available from Mouser.
