AFL Sensors AFL-Series SensorsLow Power, Low Voltage Digital Switches Features: Low voltage operation to 0.9 V Low current consumption Digital switch output Precise detection of low magnetic fields Ultra-small packages (MSOP8 and TDFN6) Available in millimeter-scale die Cannot be damaged by large magnetic fields Description: NVEs AFL-Series Sensors are digital switches designed to run at very low voltages and currents. The parts can operate from a single battery. The output is configured as a switch to detect magnetic fields, switching on at a specified magnetic field, and off when the field is removed. Current-sinking or current-sourcing output configurations are available. Both configurations supply up to 100 A. An external pull-up or pull-down resistor is required. The devices are available in MSOP8 or TDFN6 packages, or in die form. AFL Product Selection Guide AFL-Series part numbers follow the general form below. The first x in the part number specifies the voltage range, the second x denotes the output configuration, the third x specifies the magnetic operate point, and the last character pair specifies the package. The following sections define these options. AFLxxx-xx Package Type Voltage Range of Magnetic Output Operation Operate Point - 1 - www.nve.com phone: 952-829-9217 fax: 952-829-9189 AFL Sensors Voltage Range of Operation The first numeric digit of the part number in the form AFLxxx-xx specifies the operating voltage range. Four ranges are available: NVE AFL xxx-xx Number Voltage Range of Operation 0 0.9 V 1.3 V 1 1.8 V 2.5 V 2 2.7 V 3.6 V 3 4.5 V 5.5 V The quiescent supply current specifications apply within these ranges. Parts may be operated at higher voltage than shown up to a maximum of 7 V, but the quiescent current will increase. For example, a 1xx-xx part can be operated up to 3.0 V although it might it exceed the quiescent current specification. NVE can supply custom parts for different voltage ranges. Minimum order quantities, special pricing, NRE charges, and lead times may apply. Please contact NVE with your requirements. Output The second digit of the part number specifies the output configuration. Four output types are available: NVE AFL xxx-xx Number Output Type 0 Normally Off, Current Sink 1 Normally On, Current Sink 2 Normally On, Current Source 3 Normally Off, Current Source Normally Off means that with no magnetic field applied the output will not provide current when the magnetic field is applied, the output current will turn on. Normally On is opposite. Parts will sink or source up to 100 A. Output current is not included in the quiescent current specification. - 2 - www.nve.com phone: 952-829-9217 fax: 952-829-9189
