Description The TLE5555i C is a differential magnetic speed sensor based on tunnel magnetoresistance (TMR) sensing technology. This technology enables best-in-class jitter and air gap performance and allows sensing flexibility in top and side read configuration. It basic function is provide information about the rotational speed and the direction of the rotation to the transmission control unit. Therefore the sensor family includes a sophisticated algorithm which actively suppress vibration. The output has been designed as a two wire current interface based on a PWM (pulse width modulation) principle. The TLE5555i C operates without external ponents and is fully EMC-pliant thanks to its capacitor integrated on silicon level. The "ME" family members are designed for magnetic encoder (ME) applications. It es in a Ro HS pliant two-pin-package, qualified for automotive usage. For toothed...
