ACS37002LMC
Overview
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.
- 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 hysteresis
- Adjustable fast overcurrent fault □ 1 µs typical response time □ Pin adjustable threshold
- Externally configurable gain settings using two logic pins □ Four adjustable gain levels for increased design flexibility Continued on the next page… PACKAGE: 16-pin SOICW (suffix MC) Not to scale
