Hall-Effect Speed And Direction Sensor Includes Hysteresis Detection
Allegro MicroSystems

The A1232 Hall-effect speed and direction sensor IC with hysteresis detection is suitable for use in ring magnet based speed and direction systems in harsh automotive and industrial environments. Allegedly, it is the first device of its kind with the ability to detect when it powers up in the magnetic hysteresis band. This feature reduces angle accuracy error, which can occur when edges are missed at start-up. Other features include an integrated voltage regulator, short-circuit protected outputs, internal Zener clamps, reverse-battery protection, and a -40°C to +150°C operating temperature range. Available in an eight-pin, surface-mount TSSOP (suffix LE), pricing is $1.01 each/1,000. A datasheet is available at http://www.allegromicro.com/en/Products/Magnetic-Digital-Position-Sensor-ICs/Dual-Element-Switches/A1232.aspx
