Diodes Incorporated (Diodes) (Nasdaq: DIOD) adds the AH371xQ
series of high-voltage Hall-effect latches to its product
portfolio. These automotive-compliant devices feature a proprietary
Hall plate design that boosts performance. They are used for
brushless DC (BLDC) motor control, valve operation, linear and
incremental rotary encoders, and position-sensing functions. Based
on this, the AH371xQ series can support numerous in-vehicle comfort
and engine management applications—including window power-lift and
sunroof movement, tailgate opening/closing mechanisms, seat
adjustment motors, cooling fans, water/oil pumps, and speed
measurement.
These Hall-effect latches have an operating voltage range from
3V to 27V, with 40V load dump protection. This gives them the
versatility to integrate into a wide variety of automotive systems.
The devices have a chopper-stabilized design that mitigates the
effects of thermal variation and provides enhanced stray field
immunity. Their power-on time is typically 13µs.
Covering 25 gauss to 140 gauss, there is a selection of six
sensitivity options, with tight operating windows and low
temperature coefficients for switch points. These options give
engineers scope for different magnetic operating (BOP) and magnetic
release (BRP). Consequently, they can find the best fit in relation
to the sensing distance and the magnets used. Open-drain outputs
lead to greater external pull-up flexibility when it comes to
voltages that are higher or lower than the supply voltage.
The latches in the AH371xQ series have an 8kV human body model
(HBM) electrostatic discharge (ESD) rating. Protection features
integrated into each of these devices include reverse blocking
diode, overcurrent protection, and overvoltage clamp.
These new automotive-compliant Hall-effect latches from Diodes
are AEC-Q100 Grade 0 qualified, manufactured in IATF 16949
certified facilities, and support PPAP documentation. The AH371xQ
family is available in SOT23 (Type S), SC59, and SIP-3 (Bulk Pack)
packages, while the AH3712Q is also supplied in U-DFN2020-6 (SWP)
packages. The AH371xQ series is available at $0.32 in 1,000 piece
quantities. These, and the full portfolio of Hall-effect sensors,
are included in the Hall-effect sensor part selector.
