The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output driver, all in a single package. The low operating voltage and extended choice of temperature range make it suitable for use in automotive, industrial and consumer low voltage applications. The devices are delivered in a Small Outline Transistor (SOT23) for surface mount process and in a Plastic Single In Line (TO-92 flat) for through- hole mount. Both 3-lead packages are RoHS compliant. |
