ACS37002LMABTR-066B5

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 common- mode magnetic fields.

The package construction provides high isolation by magnetically coupling the field generated by the current in the conductor to the monolithic Hall sensor IC which has no physical connection to the integrated current conductor. The MA package is optimized for higher isolation with dielectric withstand voltage, 3125Vₚ₋ₚ and 0.85mΩ conductor resistance. The LA package is optimized for lower noise with 2250Vₚ₋ₚ dielectric withstand voltage and 1mΩ conductor resistance.

The ACS37002 has functional features that are externally configurable and robust without the need for programming. Two logic gain selection pins can be used to configure the device to one of four defined sensitivities and corresponding current ranges. A fast overcurrent fault output provides short- circuit detection for system protection with a fault threshold that is proportional to the current range and can be set with an analog input. The reference pin provides a stable voltage that corresponds to the 0A output voltage. This reference voltage allows for differential measurements as well as a device- referred voltage to set the overcurrent fault threshold.

Devices are RoHS compliant and lead (Pb) free with 100% matte- tin- platted leadframes.
