Hall Effect Sensor 5mA Unipolar|Bipolar 5V 3-Pin SSO

The linear Hall IC TLE4998C3C has been designed specifically to meet the requirements of highly accurate angle and position detection as well as for current measurement applications. Two capacitors are integrated on the lead frame, making this sensor especially suitable for applications with demanding EMC requirements. The sensor provides a digital SPC (Short PWM Code) signal, based on the standardized SENT (Single Edge Nibble Transmission, SAE J2716) protocol. The SPC protocol allows transmissions initiated by the ECU.
