Product details
Overview
AH180-PG-A from Diodes Incorporated is an obsolete but still available micropower omnipolar Hall-effect switch IC designed for cover-detection and contactless switching in portable electronics. It operates from 2.5V to 5.5V, consumes only 8–24 µA average supply current at 3V, and features open-drain output with ±40–60 G operate point and 15 G hysteresis. Used in clam-shell phone covers and notebook lid detection.
For engineers reviewing the AH180-PG-A datasheet, AH180-PG-A pinout, AH180-PG-A application, or AH180-PG-A equivalent, key selection criteria include magnetic sensitivity (Bop/Brp), ultra-low power consumption (<24 µW at 3V), SIP-3 package compatibility, and open-drain output drive capability for direct interface with microcontroller GPIOs.
Technical Context
The AH180 employs dual Hall plates and chopper-stabilized architecture to cancel offset drift and ensure stable switching across temperature (−40°C to +85°C). Its omnipolar response enables activation by either north or south magnetic pole orientation without polarity dependency.
It uses internal logical latch and power-switch circuitry to maintain output state until magnetic field drops below release point (Brp). The 75–125 µs awake time and 75–125 ms sampling period define its low-duty-cycle operation mode optimized for battery longevity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5V to 5.5V - supports single-cell Li-ion and 3.3V/5V logic rails without regulation. |
| Avg. Supply Current | 8–24 µA at 3V - enables multi-year battery life in always-on cover-sense applications. |
| Operate Point (Bop) | ±40–60 G - reliably triggers with small neodymium magnets at typical air gaps (1–3 mm). |
| Hysteresis (Bhy) | 15 G minimum - prevents chatter during slow magnetic field transitions near threshold. |
| Output Type | Open-drain - allows flexible pull-up to host voltage (e.g., 1.8V/3.3V) and wired-OR configuration. |
| ESD Rating | >6 kV HBM - ensures robustness during manual handling and PCB assembly. |
| Operating Temp | −40°C to +85°C - qualified for consumer portable equipment ambient conditions. |
Pinout & Package
AH180-PG-A is supplied in SIP-3 (Straight Inline Package, 3-pin) Ammo Pack format - a through-hole package with 14.5 mm body length, 3.0 mm width, and 1.5 mm height. Pin 1 = VDD, Pin 2 = GND, Pin 3 = OUTPUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Accepts 2.5–5.5V; internal regulator not required; decoupling capacitor (10–100 nF) recommended. |
| 2 - GND | Ground reference | Common return path for Hall sensor, amplifier, and output stage; must be low-impedance. |
| 3 - OUTPUT | Open-drain digital output | Sinks up to 1 mA; requires external pull-up resistor (10–100 kΩ); active-low logic signal. |
Key Features
| Feature | Design Value |
|---|---|
| Omnipolar magnetic sensing | Activates with either N- or S-pole - eliminates magnet orientation constraints in mechanical assembly. |
| Chopper-stabilized architecture | Reduces thermal drift of Bop/Brp to <±1.5 G/°C - maintains consistent switching over full temperature range. |
| Micropower operation | 24 µW typical power at 3V - enables integration into energy-constrained wearables and IoT sensors. |
| RF noise immunity | Validated against common 900 MHz/2.4 GHz emissions - prevents false triggering near wireless transceivers. |
| Lead-free & Green compliant | Meets RoHS 3 (2015/863/EU), <900 ppm Br+Cl, <1000 ppm Sb - suitable for global consumer product compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar omnipolar Hall-effect switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL33130A-15-TB | Higher Bop (±50–85 G), 1.8–5.5V supply, SC59-only packaging | Requires tighter magnet alignment; better suited for high-noise industrial enclosures | Select when wider supply range and higher ESD (8 kV HBM) are mandatory. |
| DRV5013AGQLPGMQ1 | Automotive-grade (AEC-Q100), bipolar operation only, 2.7–38V supply, 3-pin SOT-23 | Not omnipolar; requires dedicated N- or S-pole magnet; rated for under-hood environments | Choose only for automotive infotainment bezel switches requiring PPAP documentation. |
Compared with AL33130A-15-TB and DRV5013AGQLPGMQ1, AH180-PG-A offers lower power (24 µW vs. 65 µW), true omnipolarity, and SIP-3 through-hole mounting-making it optimal for cost-sensitive, space-tolerant consumer clamshell designs where automotive qualification is unnecessary.

FAQ
Is AH180-PG-A still in production?
No - AH180-PG-A is officially marked obsolete per Diodes' DS31023 Rev. 20-2 (July 2020). However, Aetrix Electronics maintains legacy inventory and offers controlled distribution with full traceability, including original Diodes date codes and packaging documentation.
What is the difference between AH180-PG-A and AH180-PG-B?
AH180-PG-A is packaged in SIP-3 Ammo Pack (4000 units/box, spread leads), while AH180-PG-B uses SIP-3 Bulk Pack (1000 units/bag, straight leads). Both share identical die, electrical specs, and marking code "180"; only mechanical lead form and packaging differ.
Can AH180-PG-A replace AH180-WG-7 in SC59 footprint?
No - AH180-PG-A uses SIP-3 (3-pin through-hole), whereas AH180-WG-7 uses SC59 (3-pin SOT-23 surface-mount). They are not physically or thermally interchangeable; pad layout, reflow profile, and board space requirements differ significantly.
Does AH180-PG-A require an external capacitor?
Yes - Diodes recommends a 10–100 nF ceramic decoupling capacitor between VDD and GND, placed as close as possible to the SIP-3 pins. This stabilizes supply during magnetic sampling and improves RF noise immunity per DS31023 Section 4.
