ACS37002LMC High Accuracy Current Sensor

The ACS37002LMC is a fully integrated Hall-effect current sensor in an SOICW-16 package that is factory-trimmed to provide high accuracy over the entire operating range without the need for customer programming. The current is sensed differentially by two Hall plates that subtract out interfering external common-mode magnetic fields. The package construction.

Features

• Low internal primary conductor resistance (0.27 mΩ) for better power efficiency and low heat dissipation
• High operating bandwidth and response time to enable reliable current measurements in applications where fast control loops are used or high-speed currents are monitored □ 400 kHz bandwidth □ 1.1 µs typical response time
• High accuracy current measurements □ ±1.5 % maximum sensitivity error over temperature □ ±10 mV maximum offfset voltage over temperature □ Non-ratiometric operation with VREF output □ Differential sensing for high immunity to external magnetic fields □ No magnetic hys.
