Product details
Overview
AH3360-FT4-7 from Diodes Incorporated is a high-sensitivity, micropower unipolar Hall-effect switch IC in X2-DFN2015-6 package, operating from 1.6V to 3.6V with 4.3µA average supply current at 1.85V. It activates on south-pole magnetic field exposure (BOP = 30 G typ), outputs open-drain low-state signal, and features chopper stabilization for ±10 G hysteresis and <0.1 µA off-state leakage - deployed in lid-detect and holster-sense functions of portable electronics.
For engineers reviewing the AH3360-FT4-7 datasheet, AH3360-FT4-7 pinout, AH3360-FT4-7 application, or AH3360-FT4-7 equivalent, key selection criteria include magnetic operate/release points across temperature, ultra-low sleep current (2.5 µA), no-external-pull-up operation, and compatibility with space-constrained PCB layouts using the 2.0 mm × 1.5 mm DFN package.
Technical Context
The AH3360-FT4-7 implements a chopper-stabilized Hall sensor with integrated sleep/awake logic, delivering stable switching thresholds (BOP = 30 G, BRP = 20 G typ) over −40°C to +85°C. Its hibernating clocking system cycles between 50 µs awake and 100 ms period, achieving 0.1% duty cycle to minimize power draw.
Internal pull-up/pull-down circuitry eliminates external resistors; output is open-drain with VOL = 0.1 V @ 1 mA sink and VOH ≥ VDD−0.2 V when off. ESD rating is 8 kV HBM, and magnetic sensitivity is specified only for south-pole activation toward the part marking side.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.6 V to 3.6 V - supports single-cell Li-ion and coin-cell battery systems without regulation. |
| Avg. Supply Current | 4.3 µA @ 1.85 V - enables multi-year operation in battery-powered lid/cover detection. |
| Operate Point (BOP) | 30 G typ (14–46 G over temp) - reliably triggers with small magnets at ≥1.5 mm air gap. |
| Release Point (BRP) | 20 G typ (9–39 G over temp) - provides 10 G hysteresis to prevent chatter near threshold. |
| Output Type | Open-drain, active-low - directly interfaces with MCU GPIO or logic inputs without level-shifting. |
| ESD Rating | 8 kV HBM - withstands handling and assembly stress in high-volume consumer manufacturing. |
| Operating Temp | −40°C to +85°C - qualified for industrial and automotive cabin-ambient environments. |
Pinout & Package
X2-DFN2015-6 is a 2.0 mm × 1.5 mm, 0.30 mm profile, 6-pin leadless package with exposed thermal pad; pin 1 marked by dot, pins 2–3 and 5 are NC (no internal connection), pin 4 is GND, pin 6 is OUTPUT, and pin 1 is VDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply input | Accepts 1.6–3.6 V; internal regulator powers analog and digital blocks. |
| 2, 3, 5 (NC) | No connection | Internally unconnected; may be left floating or tied to GND for mechanical stability. |
| 4 (GND) | Ground reference | Return path for Hall sensor, logic, and output driver; must be low-impedance. |
| 6 (OUTPUT) | Open-drain output | Sinks up to 3 mA; requires external pull-up if interfacing with higher-voltage logic. |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized architecture | Reduces offset drift to <±0.5 G/°C, enabling stable BOP/BRP across full temperature range. |
| Hibernating clocking system | Enables 0.1% duty cycle, reducing average current to 4.3 µA while maintaining 100 ms response latency. |
| Integrated pull-up/pull-down | Eliminates need for external bias resistors, saving PCB area and BOM cost in compact designs. |
| South-pole unipolar activation | Ensures deterministic turn-on only when magnet approaches marked side - prevents false triggers from stray fields. |
| RF noise immunity | Validated against common cellular and Wi-Fi band interference; no external filtering required. |
Applications
| Cellular Phone Lid Detection | Tablet Holster Sensing |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unipolar Hall-effect switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL3360QFT4-7 | Same pinout and sensitivity, but AEC-Q100 Grade 1 qualified; BOP/BRP tighter (±2 G vs ±5 G). | Required for automotive interior modules (e.g., center console lid sensing); not needed for consumer portables. | Select AL3360QFT4-7 only if automotive qualification and tighter magnetic tolerance are mandatory. |
| TLE4913-2SA | Higher supply range (2.7–24 V), 10 mA output drive, but 12 µA avg. current; SOT-23-3 package. | Used in 12 V industrial controls; incompatible with sub-2 V battery rails and space-constrained layouts. | Choose TLE4913-2SA only for wide-VIN industrial systems where 4.3 µA efficiency is secondary to drive strength. |
Compared with AL3360QFT4-7 and TLE4913-2SA, AH3360-FT4-7 uniquely balances ultra-low power (4.3 µA), 1.6 V minimum operation, and 2.0 mm × 1.5 mm footprint - making it optimal for space- and energy-constrained portable consumer devices where automotive or high-VIN specs are unnecessary.

FAQ
What is the magnetic polarity requirement for AH3360-FT4-7 activation?
The AH3360-FT4-7 activates exclusively with a south pole applied to the part marking side. North-pole exposure produces no output change. The device's unipolar behavior is confirmed in the datasheet's magnetic characteristics table and functional block diagram, with BOP/BRP values specified only for south-pole orientation.
Can AH3360-FT4-7 operate below 1.6 V?
No - the absolute minimum functional supply voltage is 1.6 V per the Recommended Operating Conditions table. Operation below this voltage risks undefined output states and failure to sample magnetic fields; the 6 V absolute maximum rating applies only to transient stress, not sustained operation.
Is an external capacitor required for stable operation?
Yes - a 100 nF ceramic capacitor (CIN) between VDD and GND is recommended per the Typical Applications Circuit. It stabilizes the internal power rail and enhances RF noise immunity; omission may cause erratic switching or increased current consumption in noisy environments.
How does the hibernating clocking system affect response time?
The hibernating system imposes a 100 ms typical period with 50 µs awake window, meaning the device samples magnetic field only once per cycle. After magnetic application, the output updates within ≤100 ms; this latency is inherent to its micropower design and documented in the tPERIOD specification.
