1、描述
The ES1220 is a Latch Hall effect sensor IC fabricated from BCD technology. The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation system, Schmitt trigger and an open-drain output driver with over-current protection, all in a single package.
It incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points. There are many applications for this sensor in addition to those listed above. The design, specifications and performance have been optimized for commutation applications in 5V to 12V brushless DC motors.
Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in automotive, industrial and consumer applications.
The device is delivered in a Small Outline Transistor (SOT/DFN) 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.
