REDROCK® RR122-3CU2-515 REDROCK® RR122-3CU3-515 ® TMR DIGITAL PUSH-PULL MAGNETIC SENSOR WITH TURBO MODE 1 Description 2 Features The RedRock® RR122-3CU2-515 and RR122-3CU3-515 are digital magnetic sensors ideal for use in medical, industrial, automotive, and consumer applications, based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. u Operate sensitivity from -10 G to +10 G Lowest Average Current < 600 nA u Wide Supply Voltage Ranges Available Down to 1.7V, Up to 5.5V u Bipolar Latching Push-Pull Response u Operating Frequencies up to 10 kHz u Toggleable 10 kHz “Turbo Mode” Available u Temperature Rated up to 125°C u RoHS & REACH Compliant u The RR122-3CU2-515 and RR122-3CU3-515 feature an operate sensitivity of 10 G (1.0 mT) with a bipolar magnetic field response. The wide supply voltage range from 1.7 up to 5.5 V is ideal for applications ranging from small battery-powered electronics to industrial machinery. They have low average current drain (600 nA) for an active magnetic sensor with an operating frequency up to 10 kHz and high operating temperature ranges from -40°C up to 125°C. 3 Applications Proximity Detection Linear Position Sensing u Rotary Sensing u Fluid Level Detection u Door & Lid Closure Detection u Utility Meters u Portable Medical Devices u Motor Controllers u Consumer Electronics u Wake-Up mProcessor u u The RR122-3CU2-515 and RR122-3CU3-515 have an available “turbo” mode that can be toggled via an input pin when faster than usual sampling is required. When provided a logic "high" signal from a microcontroller or similar, it switches the base internal clock frequency up to 10 kHz. This is particularly useful for maximizing battery life in applications involving intermittent high speed rotation sensing, where a slow clock is sufficient to detect the start of rotation but then a faster sampling period is needed to ensure that no rotations are missed.

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 1.0mF, placed not more than 10 mm from the sensor, is required.

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. 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.
