RR111-1DC2-331

SOT-23-3 REDROCK RR111 SERIES TMR ANALOG MAGNETIC SENSOR 1 Description 2 Features u Zero Hysteresis The RedRock RR111 Series is a magnetic sensor with a continu- u Low Current of 1.5 mA ous analog output linearly proportional to an applied magnetic u Omnipolar Sensitivity field. Ideal for use in medical, industrial, automotive, and consumer u Continuous Operation applications, they are based on patented Tunneling Magnetoresis- u Temperature Rated up to 85C tance (TMR) technology with seamless CMOS integration. The RR111 u RoHS & REACH Compliant enables applications like proximity sensing, and continuous level detection. 3 Applications The RR111 features a low average current drain (1.6 mA) for a u Proximity Detection continuously active magnetic sensor and temperature range from u Rotary Sensing -40C up to 85C. It comes in an SOT-23-3 package measuring u Fluid Level Detection 2.9 x 1.6 x 1.2 mm as well as an LGA-4 package measuring just u Door & Lid Closure Detection 1.4 x 1.4 x 0.45 mm. u Utility Meters u Portable Medical Devices Device Information u Motor Controllers u Consumer Electronics Part Series Package Body Size (mm) u Wake-Up mProcessor SOT-23-3 2.9 x 1.6 x 1.2 RR111 LGA-4 1.4 x 1.4 x 0.45 Device Packages Please note: This Product Series is approaching end of life and is NOT recommended for new designs.
