Specifications

The SHV-06JNV1 typically operates from a supply voltage of 3.8V to 24V and has a wide operating temperature range, often from -40°C to 150°C. It requires a magnetic field strength greater than the operate point (BOP) to switch the output high and a field strength less than the release point (BRP) to switch the output low. Specific values for BOP and BRP are provided in the Allegro MicroSystems datasheet. The output is typically an open-collector or open-drain configuration, requiring an external pull-up resistor. Refer to the official datasheet for precise specifications.
