Product details
Overview
AH3713Q-SA-7 from Diodes Incorporated is an AEC-Q100 Grade 0 qualified automotive Hall-effect latch IC in SOT23 (Type S) package, designed for brushless DC motor commutation and RPM sensing. It operates from 3.0V to 27V, features ±30G to ±45G magnetic operate/release points (BOP/BRP), open-drain output with 60mA sink capability, and chopper-stabilized architecture for stable switching across −40°C to +150°C.
For engineers reviewing the AH3713Q-SA-7 datasheet, AH3713Q-SA-7 pinout, AH3713Q-SA-7 application, or AH3713Q-SA-7 equivalent, this device supports high-reliability position sensing in harsh automotive environments where supply robustness (40V load dump), ESD immunity (8kV HBM), and bipolar latching behavior are critical selection criteria.
Technical Context
The AH3713Q-SA-7 implements a chopper-stabilized Hall sensor with dynamic offset cancellation, delivering minimal switch-point drift over temperature and superior immunity to mechanical stress. Its internal bandgap regulator supplies temperature-compensated bias to analog circuitry, enabling stable operation across the full −40°C to +150°C range.
It uses a single open-drain output with integrated overcurrent limiting (30–60mA) and Zener clamping (36V), paired with reverse-blocking diode protection on VDD. Magnetic polarity response is defined per package: South pole to part-marking side activates the output in SOT23 (Type S), matching the AH3713Q's ±30G typical BOP and ±15G typical BRP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0V to 27V - supports direct connection to automotive battery rails including cold-crank and load-dump transients. |
| Operating Temperature | −40°C to +150°C - qualified for under-hood and transmission-mounted applications per AEC-Q100 Grade 0. |
| BOP / BRP (Typical) | +30G / −30G - enables reliable latching at low-field strengths with 60G hysteresis for noise immunity in noisy engine bays. |
| Output Type | Open-drain, 60mA sink - interfaces directly with standard pull-up resistors and microcontroller GPIOs without level-shifting. |
| Startup Time | 13µs typical - ensures rapid system readiness after power-on, critical for real-time motor control loops. |
| ESD Rating | HBM: 8kV, CDM: 1kV - exceeds automotive ESD requirements for assembly and field reliability. |
| Load Dump Protection | 40V transient rating - withstands ISO 7637-2 Pulse 5a without external protection components. |
Pinout & Package
SOT23 (Type S) package: 3-pin surface-mount, lead-free, RoHS-compliant, footprint compatible with JEDEC TO-236AB. Thermal resistance θJA = 542°C/W; max power dissipation = 230mW at TA = 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Accepts 3.0–27V; includes reverse-blocking diode and 36V Zener clamp for fault tolerance. |
| 2 - GND | Ground reference | Low-impedance return path for internal circuits and output current; must be connected before VDD. |
| 3 - OUTPUT | Open-drain output | Sinks up to 60mA when activated by South pole; requires external pull-up for logic-high state. |
Key Features
| Feature | Design Value |
|---|---|
| Bipolar latching logic | South pole activates, North pole deactivates - eliminates need for external signal conditioning in rotary position sensing. |
| Chopper stabilization | 500kHz chopping frequency - reduces thermal drift of BOP/BRP to <±0.5G/°C, ensuring consistent timing in BLDC commutation. |
| Integrated protection | Reverse-battery (-18V), load-dump (40V), and output Zener clamp - removes requirement for discrete TVS or diodes in PCB layout. |
| Stress-resistant design | Qualified to AEC-Q100 Grade 0 with 170°C max junction temperature - sustains mechanical vibration and thermal cycling in drivetrain modules. |
| RF noise immunity | Validated per ISO 11452-2 - maintains clean switching in proximity to ignition systems and high-power inverters. |
Applications
| BLDC Motor Commutation | RPM Measurement |
|---|---|
|
Use Scenario: Detecting rotor position in 3-phase brushless DC motors for electronic throttle control and HVAC blower units. IC Role / Device Role / Timing Role: Provides edge-aligned commutation signals synchronized to magnet pole transitions; latched output eliminates bounce during slow-speed rotation. Use Value: Enables precise 120° electrical phase alignment with <1µs propagation delay variation across temperature, reducing torque ripple by >15% versus non-chopped Hall sensors. |
Use Scenario: Measuring rotational speed of crankshafts, camshafts, and wheel hubs in engine management and ABS systems. IC Role / Device Role / Timing Role: Generates clean, jitter-free pulse trains proportional to shaft speed; startup time ≤13µs ensures immediate RPM reporting after ignition. Use Value: Delivers accurate low-RPM counting down to 10 RPM with no missing pulses, due to 30G BOP sensitivity and 60G hysteresis rejecting EMI-induced false triggers. |
| Flow Meter Sensing | Angular Position Indexing |
|
Use Scenario: Monitoring fluid flow in fuel, coolant, and oil lines using rotating impeller with embedded magnets. IC Role / Device Role / Timing Role: Latches on each magnet pass to generate fixed-width pulses; open-drain output drives long cables to remote ECUs. Use Value: Maintains pulse integrity over 2m cable runs at 125°C ambient thanks to 60mA drive strength and built-in RF filtering via chopper architecture. |
Use Scenario: Detecting angular index marks on steering column gears or transmission selector drums for position feedback. IC Role / Device Role / Timing Role: Acts as zero-reference detector with repeatable ±0.5° electrical angle accuracy across life cycle. Use Value: Achieves <±1.2° total angular error over −40°C to +150°C due to <0.25V output saturation voltage and minimal BOP drift (<±2G). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL3713QSA-7 (Allegro) | Higher BOP (±45G typ), 5V-only supply, no load-dump rating | Limited to 5V systems; lacks 40V transient protection required for 12V/24V automotive battery rails | Select only for low-voltage, low-noise cabin modules where supply regulation is guaranteed. |
| TLE4961-3U (Infineon) | Push-pull output, 3.3V/5V supply, AEC-Q100 Grade 1 (−40°C to +125°C) | Lower temperature rating excludes under-hood use; push-pull eliminates external pull-up but increases quiescent current | Prefer for cost-sensitive body-control modules operating below 125°C ambient. |
Compared with AL3713QSA-7 and TLE4961-3U, the AH3713Q-SA-7 uniquely combines wide 3–27V operation, Grade 0 temperature range, and integrated 40V load-dump protection-making it the only drop-in solution for high-reliability engine bay position sensing without supplemental protection circuitry.

FAQ
What is the magnetic polarity configuration for AH3713Q-SA-7 in SOT23 (Type S) package?
The AH3713Q-SA-7 in SOT23 (Type S) requires the South pole applied to the part-marking side to activate the output (BOP = +30G typ), and North pole to the same side to release (BRP = −30G typ). This polarity orientation is fixed per package type and verified in DS46067 Rev. 1–2 Figure 1.
Does AH3713Q-SA-7 require an external capacitor on VDD?
Yes - a 10nF to 100nF ceramic decoupling capacitor (CIN) is required between VDD and GND per DS46067 Section "Typical Applications Circuit". It stabilizes the internal bandgap regulator and enhances RF noise immunity; omission risks erratic switching during EMI events.
Can AH3713Q-SA-7 interface directly with a 3.3V microcontroller GPIO?
Yes - its open-drain output is voltage-agnostic and compatible with 3.3V logic when paired with a 3.3V pull-up resistor. The output saturation voltage is ≤0.42V at 20mA, ensuring valid LOW-level recognition; no level shifter is needed.
Is AH3713Q-SA-7 pin-compatible with other AH371xQ variants?
Yes - all AH371xQ variants (AH3713Q through AH3717Q) share identical SOT23 (Type S), SC59, and SIP-3 pinouts and footprints. Only magnetic sensitivity (BOP/BRP) differs; electrical and thermal characteristics remain consistent across the family.
