Note: The most straightforward way of aligning a magnet with a TMR sensor is by lining up the magnet’s
magnetization axis with the sensor’s Axis of Sensitivity (as shown above). 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.

6 Application Information
RR122 Push-Pull Output Application Circuit
The output voltage on the RR122 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 input 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.

10 Suggested Pb-Free Reflow Profile
Notes:
1. 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. 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.
