RR121-1F23-311

REDROCK™ RR121 SERIES TMR DIGITAL PUSH-PULL MAGNETIC SENSOR ® 1 Description 2 Features The RedRock™ RR121 Series is a magnetic sensor with digital pushpull output 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 The RR121 features available operate sensitivities from 9 G (0.9 mT) to 70 G (7 mT), and either omnipolar, unipolar, or bipolar magnetic field response. It has the world’s lowest average current drain (200 nA) for an active magnetic sensor, as well as operating frequencies up to 10 kHz and high operating temperature ranges from -40°C up to 125°C.

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. page 20 | Copyright 2020.

Fully compatible with standard no-lead solder profile, 260 ºC for 30 seconds max (3 cycles max). 2. Profile shown as example. Users are advised to develop their own board-level profile. 3. Suggested Pb-free reflow profile derived from IPC/JEDEC J-STD-020E. 4. Temperature tolerance: +0 ºC, as measured at any point on the package or leads 5. MSL rating of 1 (SOT-23-3 only) compatible with J-STD-020 or equivalent. 6. MSL rating of 3 (LGA-4 and Leaded LGA-4) compatible with J-STD-020 or equivalent. 7. All temperatures refer to the center of the package, measured on the package body surface that is facing up during assembly reflow (e.g., livebug). If parts are reflowed in other than the normal live bug assembly reflow orientation (i.e., dead-bug), Tp shall be within ± 2 °C of the live bug Tp and still meet the Tc requirements, otherwise, the profile shall be adjusted to achieve the latter. To accurately measure actual peak package body temperatures, refer to JEP140 for recommended thermocouple use. 8. Reflow profiles in this document are for classification/preconditioning and are not meant to specify board assembly profiles. Actual board assembly profiles should be developed based on specific process needs and board designs and should not exceed the parameters in this table. 260ºC Max. Ramp Up Rate = 3ºC/s Max.
