HMC1051/HMC1052/HMC1053 are high-performance magnetoresistive sensor chips with features such as miniature surface-mount packages, wide ±6 Gauss field range, 1.0 mV/V/gauss sensitivity, and low power operation.
The Honeywell HMC1051, HMC1052 and HMC1053 are miniature surface‑mount magnetoresistive sensors offering one‑, two‑, and three‑axis magnetic field detection. They use a Wheatstone bridge and patented on‑chip set/reset and offset straps to provide high sensitivity and low power operation.
The datasheet lists electrical specifications such as a ±6 Gauss full‑scale range, 1.0 mV/V/gauss sensitivity, and bandwidth up to 5 MHz, along with pin‑out diagrams and example compassing circuits. Applications include navigation, attitude reference, traffic detection, medical devices, and position sensing.
| Supply Voltage (Vbridge) | 1.8 V min / 3.0 V typ / 20 V max |
|---|---|
| Bridge Current | 10 mA |
| Operating Temperature Range | -40 °C to 125 °C |
| Full‑Scale Field Range | ±6 Gauss |
| Sensitivity | 1.0 mV/V/gauss |
| Noise Density (1 kHz, Vbridge=5 V) | 50 nV/√Hz |
| Bandwidth | 5 MHz (lower limit = DC) |
The sensors can measure magnetic fields up to ±6 Gauss full‑scale.
The bridge can be powered from 1.8 V minimum, typically 3.0 V, up to a maximum of 20 V.
