1 REDROCK RR SERIES TMR ANALOG MAGNETIC SENSOR Description The RedRock RR Series is a magnetic sensor with a continuous analog output linearly proportional to an applied magnetic field. Ideal for use in medical, industrial, automotive, and consumer applications, they are based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. The RR enables applications like proximity sensing, and continuous level detection. The RR features a low average current drain (.6 ma) for a continuously active magnetic sensor and temperature range from -40 C up to 85 C. It comes in an SOT-2- package measuring 2.9 x.6 x.2 mm as well as an LGA-4 package measuring just.4 x.4 x 0.45 mm.

A decoupling capacitor between the supply voltage and ground is required with placement close to the magnetic sensor. A typical capacitor value of.0 mf will suffice. The analog output voltage is proportional to the strength of an applied magnetic field. A simple RC filter is recommended at the output. A resistor value of 47kW and a capacitor value of 00 pf should suffice. page 4 Copyright 207. All rights reserved. rev

Ramp Down Rate = 6ºC/s Preheat Area 0 seconds max seconds 255ºC Temperature 50ºC seconds 25 Time 25ºC to Peak Time Notes:. Fully compatible with standard no-lead solder profile, 260 ºC for minute max ( cycles max). 2. Profile shown as example. Users are advised to develop their own board-level profile.. 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 (SOT-2- only) compatible with J-STD-020 or equivalent. 6. MSL rating of (LGA-4 only) 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., live-bug). 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 JEP40 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. page 8 Copyright 207.
