DESCRIPTION

The ACS37010 and ACS37012 are fully integrated current

sensor ICs that sense current flowing through the compact SOIC

LZ package. The current conductor has a very low 0.68 mΩ

resistance, ideal for low power dissipation constraints. The sensor

is factory-trimmed to provide high accuracy over the entire

operating range without the need for customer programming.

The internal construction provides high isolation and excellent

magnetic coupling of the field generated by the current flowing

in the conductor and the fully monolithic Hall sensor IC. The

current is sensed differentially by two Hall plates that subtract

interfering common-mode magnetic fields. The sensor provides

a very fast 1.3 μs response time analog output with VREF

pin for use in noisy supply environments (ACS37010) or a

fast logic alert fault output pin with factory pre-programmed

trip point provides overcurrent or short-circuit detection and

enhanced system protection (ACS37012). The IC has no

physical connection to the integrated current conductor and

provides 3500 VRMS of isolation between the primary and

secondary signal leads of the package. This rating provides

basic working voltage of 840 VRMS and reinforced working

voltage of 420 VRMS.

The ACS37010/12 is in a custom 6-pin SOIC package (suffix

LZ). Devices are RoHS-compliant and lead (Pb) free without the

use of RoHS exemptions with 100% matte-tin-plated leadframes.
