Installation Instructions for the SS345PT/SS445P Unipolar Hall-effect Digital Position Sensor ICs with Built-in Pull-up Resistor ISSUE 2 50048012 Table 1. Absolute Maximum Ratings1 GENERAL INFORMATION CAUTION ELECTROSTATIC DISCHARGE DAMAGE This component is sensitive to electrostatic discharge (ESD). Take normal ESD precautions in handling this product to prevent ESDinduced damage and/or degradation. Failure to comply with these instructions may result in product damage. Characteristic Supply voltage Applied output voltage Output current Magnetic flux Min. -0.5 -0.5 Typ. – – Max. 7.0 7.0 Unit Vdc Vdc – – – – 8.0 no limit mA Gauss Note 1: Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will the device necessarily operate at absolute maximum ratings. NOTICE The magnetic field strength (Gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a uniform magnetic field. SOLDERING/ASSEMBLY CAUTION IMPROPER SOLDERING Ensure leads are adequately supported during any forming/ shearing operation so that they are not stressed inside the plastic case. Limit exposure to high temperatures. Do not wave solder the SS345PT. Failure to comply with these instructions may result in product damage. SS345PT: Use an infrared reflow process with temperatures of 245 °C [473 °F] peak for 10 s max. SS445P: PC board wave soldering temperature is 250 °C to 260 °C [482 °F to 500 °F] peak for 3 s max.
