Infineon Hall Effect Sensor Unipolar Switch Surface Mount Open Drain 1.6 mA Supply Current 25 mA Output TLE49646MXTMA1

Infineon TLE49646MXTMA1 is a high-performance Hall Effect Sensor designed as a unipolar switch with surface mount packaging and an open drain output type. It operates with a supply voltage range from 3 V dc up to a maximum of 32 V dc, and a supply current as low as 1.6 mA, making it an energy-efficient choice for electronics incorporating magnetic sensing.

This sensor is engineered for demanding automotive and industrial control applications and includes robust features such as reverse polarity protection to -18 V and an overvoltage capability up to 42 V without requiring external resistors. These protections ensure sensor integrity even in fluctuating power conditions.

The device supports a maximum output current of 25 mA, adequate for activating downstream switches or microcontroller inputs. Its high stability of magnetic thresholds combined with active error compensation and low jitter (typical 0.35 microseconds) ensures accurate and repeatable switching performance.

Additional built-in protections include output overcurrent and overtemperature safeguards to maintain reliable operation under thermal and electrical stresses. It is suitable for operation within a temperature band of 40 °C to 107 °C, enabling use in tough automotive under-hood or industrial environments.

The sensor is configured as a unipolar switch type with 3G and 4G switch operation capability, providing precise magnetic field actuation. Surface mount terminals facilitate automated PCB assembly processes, enhancing manufacturing efficiency.

Applications span across automotive sensing, industrial machinery monitoring, and automation control systems where magnetic position or proximity detection is required. Operates with minimum supply voltage of 3 V dc and maximum 32 V dc.

Consumes 1.6 mA supply current at typical conditions. Maximum output current is 25 mA through open drain output. Provides reverse polarity protection and high ESD robustness. Maintains stable magnetic thresholds with active compensation.
