TLE4984CHTE6747HAMA2

P1-P2
Product Brief
The TLE4984C is an active Hall sensor ideally suited for camshaft applications in
automotive. Its basic function is to map either a tooth or a notch of a target wheel
(e.g. gear wheel) into a unique electrical output state. The magnetic switching points
thereby have a high accuracy paired with an excellent stability due to the innovative
chopped Hall technology used for this sensor. The implemented electrical trimming
option for post-fabrication trimming sets the sensor’s switching points. This ensures
its true power on capability even in the case of production spreads such as dierent
magnetic configurations or misalignment. The programmability of the sensor includes
also the option to adjust the temperature coecients to the application needs. The
standard configuration is programmed for NdFeB back bias magnets.
Additional, a self-calibration module has been implemented to achieve optimum
accuracy during normal running operation. The self calibration adjusts the osets and
is well suited to cope with symmetrical and asymmetrical target wheels.
The TLE4984C comes in a three-pin package for the supply voltage and an open drain
output. The package has two integrated capacitors for enhanced EMC micro break
performance.
