Infineon Surface Hall Effect Sensor Latch 4.5 V 5.5V, SSO, 3-Pin

The Infineon programmable linear hall sensor has been designed specifically to meet the requirements of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a digital PWM signal, which is ideally suited for direct decoding by any unit measuring a duty cycle of a rectangular signal. Furthermore, it is possible to attach an external low pass filter, which allows an A/D conversion using the sensor supply voltage as a reference. The output stage is an open-drain driver pulling the output pad to low only. Therefore, the high level must be obtained by an external pull-up resistor. This output type has the advantage that the receiver may use even a lower supply voltage. In this case, the pull-up resistor must be connected to the given receiver supply.
