ACS37002
Overview
The ACS37002 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 commonmode magnetic fields.
- High operating bandwidth for fast control loops or where high-speed currents are monitored □ 400 kHz bandwidth □ 1.1 µs typical response time
- High accuracy □ ±1% maximum sensitivity error over temperature (K series) □ ±8 mV maximum offset voltage over temperature □ Non-ratiometric operation with VREF output □ Low noise LA package ◊ 160 mVRMS for 3.3 V supply ◊ 124 mVRMS for 5 V supply □ 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 MA/LA) Not to scale
