Want to post a buying lead? If you are not a member yet, please select the specific/related part number first and then fill the quantity and your contact details in the "Request for Quotation Form" on the left, and then click "Send RFQ".Your buying lead can then be posted, and the reliable suppliers will quote via our online message system or other channels soon.
The circuit includes Hall generator, amplifier and Schmitt-Trigger on one chip. Theinternal reference provides the supply voltage for the components. A magnetic fieldperpendicular to the chip surface induces a voltage at the hall probe. This voltage isamplified and switches a Schmitt-trigger with open-collector output. A protection diodeagainst reverse power supply is integrated. The output is protected against electrical disturbances.
