霍尔效应传感器, 线性, 5 mA, SOIC, 8 引脚, 4.5 V, 5.5 V

Description:

The linear Hall IC TLE4998P8D has been designed specifically to meet the requirements of highly accurate angle and position detection. The sensor provides a digital PWM signal, which is well suited for direct decoding by any unit measuring a duty cycle of a rectangular signal usually a timer/capture unit in a microcontroller. The output stage is an open-drain driver pulling the output pin to low only. Therefore, the high level needs to be obtained by an external pull-up resistor. This output type has the advantage that the receiver may use an even lower supply voltage e.g. 3.3 V. In this case the pull-up resistor must be connected to the given receiver supply.
