SC2526H Speed, Direction & Frequency Output Hall Sensor IC

Datasheet

Description

The SC2526H is a dual-channel Hall-effect sensor IC ideal for use in speed and direction sensing applications incorporating encode ring-magnet targets. The SC2526H provides various output signals that indicate speed and direction of target rotations. The Hall elements are both photos lithographically aligned to better than 1um. Maintaining accurate displacement between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications. The SC2526H is a sensitive, temperature-stable magnetic device ideal for use in harsh automotive and industrial environments.
The Hall elements of the SC2526H are spaced 1.4mm apart, which provides excellent speed and direction information for small-geometry targets. Extremely low-drift amplifiers guarantee symmetry between the switches to maintain signal quadrature. An on-chip regulator allows the use of this device over a wide operating voltage range of 3.0 to 24V
The digital outputs are out of phase so that the outputs are in quadrature when interfaced with the proper ring magnet design. For the direction signal to be updated, a quadrature relationship must be maintained.
The SC2526H is available in a 4-pin SIP and a plastic 8-pin SOIC surface mount package. Both packages are lead (Pb) free, with 100% matte tin lead frame plating.
