Applications


The RedRock™ RR122-3C72/3C73 sensor series from Coto Technology is a range of digital push-pull magnetic sensors designed using a patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. The RR122-3C72/3C73 series features a typical operate sensitivity of 10 G (1.0 mT), with a latching bipolar magnetic field response. They offer a wide supply voltage range from 1.7V to 5.5V, ideal for applications ranging from small battery-powered electronics to industrial machinery. The TMR sensors have a typical current drain of 11μA (at 3V and operating at 2500Hz) and are available with operating temperature ranges of -40°C to +85°C (RR122-3C72-511 & RR122-3C72-512) or -40°C to +125°C (RR122-3C73-511 & RR122-3C73-512). These sensors are ideal for use in medical, industrial, automotive, and consumer applications. All of the RR122-3C72/3C73 series is available in either SOT-23-3 (511 variant) or LGA-4 packages (512 variant).
