SmartSens MS2100
The simplest way to integrate 2-axis magnetic field sensing into any device, the SmartSens MS2100 comprises two orthogonal magnetic sensors on a single chip to provide high-resolution compassing while setting new lows for energy consumption. It boasts unparalleled dynamic range, hysteresis-free performance, immunity to large-signal noise, and stability over a wide temperature range. Ideal for field sensing applications where power is in short supply, the SmartSens MS2100 is optimized for use in watches, radar detectors, and any consumer product with integrated compassing functions.
The SmartSens MS2100 combines PNI's magneto-inductive (MI) sensors and ASIC into a single package for unparalleled performance. Designed to facilitate digital compassing in consumer electronics products, the MS2100 can enable heading accuracy of 1˚with 0.5˚ resolution. The device also includes pins to support the connection of a third MI sensor axis for higher performance applications. The MS2100 uses significantly less power than comparable magneto-resistive (MR) or fluxgate sensors. And because it doesn't require setting and resetting like MR devices, its peak current requirement is dramatically less. The microprocessor-compatible SPI interface allows easy access to the MS2100's
measurement parameters, while eliminating the need for glue logic components.
3V operation ensures compatibility with most battery-powered products. Providing
software-configurable resolution, sampling rate, and measurement range, the
MS2100 can be optimized for the user's system.
These advantages make the MS2100 the choice for high volume applications where
small size and low power requirements are paramount.
