Automotive-Compliant, Two-Wire Hall Effect Switches With Self-Diagnostics From Diodes Incorporated Deliver High Sensitivity and Stable Performance
The AH324xQ and AH328xQ have integrated self-diagnostics which continually monitor the main device blocks, supply voltage, and temperature. There is a third output state that warns of an abnormal condition. These devices are ISO 26262 ASIL-B ready, having been developed using rigorous design processes with safety analysis conducted in accordance with the ISO 26262 standard.
Diodes adopted an advanced chopper stabilized design, which provides superior stability of the magnetic operating and release points (BOP/BRP) over the 2.7V to 27V operating voltage and -40˚C to +150˚C temperature range. This stability, coupled with a high ESD rating of 8kV, built-in reverse blocking diode, and supply pin Zener clamp, enables the AH32xxQ series to meet the demanding requirements of automotive proximity/position-sensing applications.
All AH32xxQ devices are supplied in the SC59 package. They are qualified to AEC-Q100, manufactured in IATF 16949 certified facilities, and support PPAP documentation. The AH324xQ and AH328xQ have a unit price starting at
