Infineon (TLE4997E2XALA1) Hall Effect Sensor, Linear, Ratiometric, 1 mA

Hall Effect Sensor, Linear, Ratiometric, 1 mA, SSO, 3 Pins, 4.5 V, 5.5 V Product Overview The TLE4997E2 is a Linear Hall Effect Sensor designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a ratiometric analogue output voltage, which is ideally suited to Analogue-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture and digital temperature compensation guarantees excellent stability over a long period of time. The minimum overall resolution is 12bits. Some internal stages work with resolutions up to 20bits.The chopped Hall-effect cell and continuous-time A to D conversion provide very low and stable magnetic offset. Magnetic flux is measured by a hall effect cell Programmable low-pass filter reduces the noise Temperature is measured and A to D converted Digital processing of output voltage is based on zero field and sensitivity value Output voltage range can be clamped by digital limiters Final output value is D to A converted Output voltage is proportional to the supply voltage (ratiometric DAC) On-board-diagnostics (OBD) circuit connects the output to VDD or GND in case of errors Applications Sensing & Instrumentation, Automotive, Test & Measurement, Motor Drive & Control Product Information Hall Effect Type: Linear, Ratiometric Output Current: 1mA Sensor Case Style: SSO No. of Pins: 3Pins Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Operating Temperature Min: -40°C Operating Temperature Max: 150°C MSL: MSL 1 - Unlimited
