APS11200: High-Temperature Precision Hall-Effect Switch

The APS11200 is a three-wire, planar Hall-effect sensor integrated circuit (IC). This device was developed in accordance with ISO 26262:2011.

This Hall-effect switch IC features extended AEC-Q100 qualification and is ideal for high-temperature operation up to 175°C junction temperatures. In addition, the APS11200 includes a number of features designed specifically to maximize system robustness such as reverse-battery protection, output current limiter, overvoltage, and EMC protection.

The single silicon chip includes: a voltage regulator, a Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit-protected open-drain output. A south pole of sufficient strength turns the output on. Removal of the magnetic field—or a north pole—turns the output off. The devices include on-board transient protection for all pins, permitting operation directly from a vehicle battery or regulator with supply voltages from 2.8 to 24 V.

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.

APS11200 was developed in accordance with ISO 26262:2011 as a hardware safety element out of context with ASIL A capability (pending confirmation) for use in automotive safety-related systems when integrated and used in the manner prescribed in the applicable safety manual and datasheet.
