Additional Details

The TLI4961-1M requires a supply voltage, typically in the range of 3V to 5.5V. The switching thresholds (Bop and Brp) specify the magnetic field strengths at which the output switches on and off, respectively. The operating temperature range and package type (e.g., SOT-23) are also important parameters. It is essential to consult the datasheet for the exact supply voltage range, switching thresholds, operating temperature range, and other critical parameters. This Hall effect sensor is a reliable and cost-effective solution for a wide range of magnetic field sensing applications, particularly in automotive and industrial sectors.
