Diodes Incorporated AH3562Q-P-A

Overview

AH3562Q-P-A from Diodes Incorporated is an AEC-Q100 Grade 0 qualified omnipolar Hall-effect switch optimized for automotive proximity sensing, featuring ±20 G operating point, ±10 G release point, open-drain output, 3 V to 28 V supply range, and -40°C to +150°C operation-used in door latch detection, seat position sensing, and gear selector feedback.

For engineers reviewing the AH3562Q-P-A datasheet, AH3562Q-P-A pinout, AH3562Q-P-A application, or AH3562Q-P-A equivalent, key selection criteria include magnetic sensitivity tolerance, reverse polarity protection (32 V), ESD robustness (8 kV HBM), temperature drift performance, and SIP-3 package compatibility with high-vibration mounting.

Technical Context

The AH3562Q-P-A implements a bipolar-latching-free omnipolar detection architecture that activates on either North or South magnetic pole exposure, enabling simplified mechanical design in rotating or linear motion systems. Its internal voltage regulator stabilizes operation across 3 V–28 V, while integrated input/output clamps and thermal shutdown ensure fault resilience.

Designed specifically for Grade 0 automotive environments, it delivers <±0.5 G typical drift over temperature and supply voltage, with factory-trimmed BOP/BRP points tightly distributed at ±20 G and ±10 G respectively-critical for repeatable hysteresis in safety-critical proximity monitoring.

FAQ

What is the magnetic sensitivity tolerance of AH3562Q-P-A over temperature and supply voltage?

The AH3562Q-P-A exhibits <±0.5 G typical variation in operating point (BOP) and release point (BRP) across its full -40°C to +150°C range and 3 V–28 V supply voltage. This tight drift specification is achieved via on-chip trimming and matched Hall element design, ensuring consistent hysteresis in safety-critical automotive applications without recalibration.

Can AH3562Q-P-A be used with a 5 V pull-up on the open-drain output?

Yes-AH3562Q-P-A's open-drain output is compatible with any pull-up voltage up to 32 V, including standard 5 V logic systems. The device sinks up to 20 mA when active, allowing direct interface with microcontroller GPIOs or relay drivers without additional level-shifting circuitry.

Is SIP-3 packaging suitable for automated through-hole assembly?

Yes-the SIP-3 package of AH3562Q-P-A is designed for wave soldering and selective soldering processes. Its 2.54 mm pin pitch, 5.0 mm body length, and axial lead form support standard pick-and-place and conveyorized through-hole assembly lines used in Tier 1 automotive electronics manufacturing.

Does AH3562Q-P-A require an external capacitor on the VDD pin?

Yes-a 0.1 µF ceramic decoupling capacitor is required between VDD and GND, placed within 5 mm of the SIP-3 pins. This ensures stable internal regulation during fast transients and suppresses high-frequency noise from automotive power rails, as specified in Diodes Inc. datasheet DS42749 Section 7.2.
