HMC1051/HMC1052/HMC1053

1, 2 AND 3-AXIS MAGNETIC SENSORS

Features

x Miniature Surface-Mount Packages
x Wide Field Range of ± 6 Gauss
x 1.0 mV/V/gauss Sensitivity
x Low Power Operation Down to 1.8V
x Patented On-chip Set/Reset and Offset Straps

Product Description

The Honeywell HMC1051, HMC1052 and HMC1053
are high performance magnetoresistive sensor designs
on a single chip (HMC1051, HMC1052) or two chips
(HMC1053). The advantages of these patented chips
include orthogonal two-axis sensing (HMC1052), ultra
small size and low cost in miniature surface mount
packages.

SENSOR PRODUCTS

Each of the magneto-resistive sensors are configured
as a 4-element wheatstone bridge to convert magnetic
fields to differential output voltages. Capable of sensing
fields down to 120 micro-gauss, these sensors offer a
compact, high sensitivity and highly reliable solution for
low field magnetic sensing.
