However, there are many other alignments and orientations that will also achieve proper operation. For any questions, or to learn more, please contact Coto Technology.

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 capacitor with a value of 1 mF, placed not more than 10 mm from the sensor, is required. 6.1 Application Circuit (SOT-23-3) 6.2 Package Pinout (SOT-23-3) GND 3 VDD GND 4 3 OUT DNC 1 2 VDD 1 1.0mF RR122 2 VOUT 1 2 VDD OUT 3 GND 7 Dimensions Millimeters (Inches) SOT-23-3 Package Top View End View 2.90 ± 0.15 (0.114 ± .006) 1.45 ± 0.20 (0.057 ± .008) 1.20 ± 0.20 (.047 ± .008) 3 2.80 ± 0.25 (.110± .010) 0.10 ± 0.10 (.004 ± .004) 0.44 ± 0.15 (.017 ± .006) 0.6 (0.024) 1.60 ± 0.15 (0.063 ± .006) 1 Side View 2 0.40 ± 0.15 (.016 ± .006) 1.90 (0.075) 1.10 ± 0.15 (.043± .006) 8 TMR Sensor Location 8.1 SOT-23-3 Package 8.2 SOT Package - Side View 3 0.76 mm 1.45 mm 1.60 mm 0.80 mm 1 2 2.90 mm (401) 943-2686 | redrock@cotorelay.com | www.cotorelay.com © Coto Technology 2022 All rights reserved. | rev.04062022 | page 5 REDROCK® RR122-1A52-511 REDROCK® RR122-1A53-511 TMR DIGITAL PUSH-PULL MAGNETIC SENSOR ® 9 TMR Sensor & Switch Packaging 9.1 SOT-23-3 Tape & Reel Packaging Standard packaging is Tape & Reel containing 3,000 pieces.

Fully compatible with standard no-lead solder profile, 260ºC 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: +0ºC, 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. 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. 7. 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.
