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

Hall Effect Sensor, Linear, Ratiometric, 1 mA, SSO, 3 Pins, 4.5 V, 5.5 VProduct OverviewThe TLE4997E2 is a Linear Hall Effect Sensor designed specifically to meet thedemands of highly accurate rotation and position detection, as well as forcurrent measurement applications. The sensor provides a ratiometric analogueoutput voltage, which is ideally suited to Analogue-to-Digital (A/D) conversionwith the supply voltage as a reference. The IC is produced in BiCMOS technologywith high voltage capability and also provides reverse polarity protection.Digital signal processing using a 16-bit DSP architecture and digitaltemperature compensation guarantees excellent stability over a long period oftime. The minimum overall resolution is 12bits. Some internal stages work withresolutions up to 20bits.The chopped Hall-effect cell and continuous-time A to Dconversion provide very low and stable magnetic offset.Magnetic flux is measured by a hall effect cellProgrammable low-pass filter reduces the noiseTemperature is measured and A to D convertedDigital processing of output voltage is based on zero field and sensitivityvalueOutput voltage range can be clamped by digital limitersFinal output value is D to A convertedOutput voltage is proportional to the supply voltage (ratiometric DAC)On-board-diagnostics (OBD) circuit connects the output to VDD or GND in case oferrorsApplicationsSensing & Instrumentation, Automotive, Test & Measurement, Motor Drive & ControlProduct InformationHall Effect Type: Linear, RatiometricOutput Current: 1mASensor Case Style: SSONo. of Pins: 3PinsSupply Voltage Min: 4.5VSupply Voltage Max: 5.5VOperating Temperature Min: -40°COperating Temperature Max: 150°CMSL: MSL 1 - Unlimited
