APS11205: High-Temperature Hall-Effect Switch for Low Voltage Applications

Description

The APS11205 Hall-effect sensor IC is an extremely temperature-stable and stress-resistant device, especially suited for operation over extended junction temperature ranges up to 175°C. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.

The single silicon chip includes: a Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a shortcircuit-protected open-drain output. A south pole of sufficient strength turns the output on. Removal of the magnetic field turns the output off. For applications requiring operation from greater than 5.5 V, or operation directly from a battery, refer to the A1120.

Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified SOT23W, surfacemount package, while UA is a three-lead ultra-mini SIP for through-hole mounting. Both packages are lead (Pb) free and RoHs compliant with 100% matte-tin leadframe plating.
