1, 2 and 3 Axis Magnetic Sensors

HMC1051/HMC1052/HMC1053

The Honeywell HMC1051, HMC1052 and HMC1053 are

magnetoresistive sensors designed for low field magnetic sensing.

Various packaging options have been created from the basic

HMC1052 sensor chip to create 1, 2 and 3-axis magneto-resistive

sensors for cost effective and small size solutions. The advantage

of the HMC105X family of sensors is in the near-perfectly

orthogonal dual sensor on a single chip with shared set/reset and

offset coils/straps included.

The HMC105X family utilizes Honeywell’s Anisotropic

Magnetoresistive (AMR) technology that provides advantages over

coil based magnetic sensors. They are extremely sensitive, low

field, solid-state magnetic sensors designed to measure direction

and magnitude of Earth’s magnetic fields, from 120 micro-gauss to

6 gauss. Honeywell’s Magnetic Sensors are among the most

sensitive and reliable low-field sensors in the industry. Applications

for the HMC105X family of sensors include low cost Compassing,

Magnetometry, and Current Sensing.

Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic

sensor solutions. These are highly reliable, top performance products that are delivered when promised. Honeywell’s

magnetic sensor solutions provide real solutions you can count on.

REFLOW AND REWORK The HMC1051ZL and HMC1053 parts should reference application note AN-216. The other part types have no special profile required and compatible with lead eutectic and lead-free solder paste reflow profiles up to 220°C. Honeywell recommends the adherence to solder paste manufacturer’s guidelines.

HMC1051/HMC1052/HMC1053 The set/reset strap can be pulsed with high currents for the following benefits: 1) Enable the sensor to perform high sensitivity measurements, 2) Flip the polarity of the bridge output voltage, and 3) Periodically used to improve linearity, lower cross-axis effects, and temperature effects.

HMC1051/HMC1052/HMC1053 APPLICATION NOTES Low Cost 2-Axis Compass Very high precision measurements can be made using the HMC105X family of sensors when interfaced with low noise amplifiers and 12 to 16-bit Analog-to-Digital (A/D) converters. For lower resolution (3° accuracy or more) or low cost compass applications, 8 or 10-bit A/D converters may be used with general purpose operational amplifiers. Figure 2 shows a typical 2-axis compassing application using readily available off-the-shelf components.

HMC1051/HMC1052/HMC1053 For operation at normal 3.3 or 5-volt logic levels, a single complementary MOSFET pair can be used in a single ended circuit shown in Figure 4. Other complementary MOSFET pairs can be used with the caution that the chosen devices should have less than 0.5 ohms ON resistance and be able to handle the needed supply voltages and set/reset currents. Note that even a 1Hz rate of set/reset function draws an average current of less than 2 microamperes.
