Allegro MicroSystems ACS37610 Current Sensor ICs
Allegro MicroSystems ACS37610 Current Sensor ICs are coreless, high-precision, and Hall-effect sensor ICs with DC to 250kHz high operating bandwidth range. These sensor ICs can measure 100A to >4000A currents flowing through a busbar or a PCB without needing a concentrator core or a U-shaped magnetic shield. The ACS37610 ICs feature a Common-Mode Field Rejection (CMFR), <2μs typical fast response time, and factory-programmed segmented linear Temperature Compensation (TC). These sensor ICs include user-programmable Over-Current Protection (OCP), Over-Temperature Protection (OTP), and a slew of built-in diagnostics.
The ACS37610 ICs come in regular and low-power modes to achieve optimal Signal-to-Noise Ratio (SNR) and power consumption. These ICs are AEC-Q100 Grade 0, automotive qualified, and are available in surface mount, small footprint, and low-profile TSSOP8 package. The ACS37610 ICs are ideal for 48V/12V auxiliary inverter, DC/DC converter, smart fuse, Power Distribution Unit (PDU), and heterogeneous redundant battery monitoring.
