Silicon Labs SI7214-B-00-IVR

霍尔效应单路PWM±20mT3.3V ~ 26.5V

Overview

A range of Hall-effect magnetic sensors from Silicon Labs featuring chopper-stabilized Hall elements, low-noise amplifiers and 13-bit ADCs which provide a linear outputs proportional to magnetic field strength. The Si721x series are available with analogue, PWM or SENT (Single Edge Nibble Transmission) outputs. Typical applications include mechanical position sensing in consumer, industrial and automotive applications, camera image stabilization, zoom, and autofocus functions, sensing of control knobs and selector switches.

• Industry-leading sensitivity allows use with larger air gaps and smaller magnets• Precise compensation for temperature and offset drift.• Low power consumption to improve operating life in battery powered applications• Low voltage (1.7-5.5V) and High voltage (3.3-26.5V) versions• Compact 3 or 5-pin SOT23 package• AEC-Q100 Qualified for automotive applications
