UH211

UNISONIC TECHNOLOGIES CO., LTD UH211 LINEAR INTEGRATED CIRCUIT HIGH SENSITIVITY HALL EFFECT SENSOR IC WITH FG OUTPUT  DESCRIPTION The UTC UH211 is a semiconducting integrated Hall Effect Sensor IC. It is just like all the hall sensitive Hall Effect Sensors designed to work in the situations which the accurate track is extremely small and the changes in magnetic flux density-changes are generally too small to be operated. Besides those features shared in all Hall Effect Sensors, UH211 can apply to various kinds of applications, such as contact-less switches, motion detectors, gear tooth sensors, proximity detectors, and electric communication of DC brushless motors, etc.  FEATURES * Hall Sensor On-Chip * Output Zener Diodes to Clamp the Peak Output Voltage * Frequency Generation Output * High Output Sinking Capability (nearly to 400mA) * High Sensitivity Hall Effect Sensor IC: ±65G  ORDERING INFORMATION Ordering Number UH211G-G04-K Package SIP-4 Packing Bulk  MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R118-014.B UH211 LINEAR INTEGRATED CIRCUIT  PIN DESCRIPTION PIN NO. 1 2 3 4 PIN NAME FG DO DOB GND DESCRIPTION Open collector pin: for rotation frequency detection Coil output or power input Coil output or Power input IC ground  BLOCK DIAGRAM  SENSOR LOCATIONS UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R118-014.B UH211 LINEAR INTEGRATED CIRCUIT  ABSOLUTE MAXIMUM RATINGS (TA=25°С, unless ot...
