REDROCK™ RR121 SERIES TMR DIGITAL SENSOR
™
1 Description
2 Features
The RedRock™ RR121 Series is a digital logic sensor ideal for use in medical, industrial, automotive, and consumer applications. Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, the RR121 offers multiple configurations of several parameters to enable applications like proximity sensing, rotary sensing, and level detection.
u
Configurable operate sensitivity from 5 G to 100 G Ultra-Low Hysteresis Available u Lowest Average Current < 190 nA u Omnipolar, Unipolar, and Bipolar Latching Responses Available u Operating Frequencies up to 333 kHz u Temperature Rated up to 125°C u RoHS & REACH Compliant u
The RR121 features available operate sensitivities from 9 G (0.9 mT) to 100 G (10 mT), and either omnipolar, unipolar, or bipolar magnetic field response. It has the world’s lowest average current drain (190 nA) for an active magnetic sensor, as well as operating frequencies up to 333 kHz and high operating temperature ranges from -40°C up to 125°C.

RR121 Output Application Circuit The output voltage on the RR121 is active low, meaning that while a sufficiently strong magnetic field is present, the output voltage is low. The output voltage can be connected to a digital I/O pin on a microcontroller. A decoupling capacitor between the supply voltage and ground is required with placement close to the magnetic sensor. A typical capacitor value of 1.0 mF will suffice.
