APS12200, APS12210, and APS12230: High-Temperature Precision Hall-Effect Latches

Description

The APS12200, APS12210, and APS12230 are three-wire, planar Hall-effect sensor integrated circuits (ICs) that feature extended AEC-Q100 qualification and are ideal for high-temperature operation up to 175°C junction temperatures. In addition, the APS12200/10/30 include 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; a north pole of sufficient strength is necessary to turn 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 3-pin SOT23W surface-mount package, while UA is a three-pin ultramini SIP for through-hole mounting. Both packages are lead (Pb) free and RoHS compliant, with 100% matte-tin-plated leadframes.

ASIL Logo

These devices wer 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. For further information, contact your local Allegro field applications engineer or sales representative.
