AS443 24V, 50~150G, Unlatched Hall Effect Position Sensor DESCRIPTION FEATURES The AS443 Bipolar Hall-Effect sensors are small, versatile digital Hall-effect devices that are operated Miniature construction: 3.0 mm x 4.0 mm [0.12 in x 0.16 in] plastic package by the magnetic field from a permanent magnet or an Operating Voltage: 3.5V to 24V electromagnet, and are designed to respond to Power consumption of only 5 mA max at 4.5 South poles. Vdc for energy efficiency A built-in regulator provides enhanced stability of Unipolar magnet for single magnet applications operation over 3.5Vdc to 24 Vdc supply voltage High speed: operates from 0 kHz to over 100 range, and internal circuitry is designed to prevent sensor damage in case the supply voltage polarity is kHz accidentally reversed. Broad temperature range of -40 °C to 150 °C [-40 °F to 302 °F] The device includes an on-chip hall voltage Built-in reverse polarity protection generator for magnetic sensing, a comparator that amplifiers the hall voltage, and a Schmitt to provide APPLICATIONS switching hysteresis for noise rejection, and open-collector output. Speed and RPM (revolutions per minute) sensing The AS443 is factory tested at 25 °C [77 °F] ORDER INFORMATION Part Number Package Packing AS443LIK SIP-3L Bulk Brushless dc (direct current) motor commutation Motor and fan control Tachometer, counter pickup Flow-rate sensing “ANI” and “ANISEM” is Trademarks of ANISEM Semiconductor, Inc.
