Product details
Overview
AH180-PG-B-S from Diodes Incorporated is a micropower omnipolar Hall-effect sensor switch in SIP-3L package, operating from 2.5V to 5.5V with 24μW typical supply power at 3V, ±40–60 G operation point, open-drain output, and -40°C to +85°C temperature range-designed for cover detection in clam-shell cellular phones.
For engineers reviewing the AH180-PG-B-S datasheet, AH180-PG-B-S pinout, AH180-PG-B-S application, or AH180-PG-B-S equivalent, key selection criteria include magnetic operate/release points, ultra-low quiescent current, RoHS-compliant green molding compound, and SIP-3L mechanical compatibility with space-constrained portable PCBs.
Technical Context
The AH180 employs dual Hall plates with chopper-stabilized architecture to cancel offset drift and deliver stable switching across temperature and supply voltage variations. Its latch-free design responds to either north or south magnetic pole orientation without polarity dependency.
It features internal power management enabling 8–24μA average supply current over full operating conditions, with 75–125μs wake-up time and 75–125ms sampling period. Output remains off in zero-field condition and pulls low only when |B| exceeds Bop (±40–60 G), releasing at Brp (±10–30 G) with ≥15 G hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5V to 5.5V - supports single-cell Li-ion and 3.3V/5V system rails without regulation. |
| Average Supply Current | 8–24 μA - enables multi-year battery life in always-on cover-sense applications. |
| Operation Point (Bop) | ±40–60 G - ensures reliable actuation with small, low-cost magnets at air gaps up to 3 mm. |
| Release Point (Brp) | ±10–30 G - provides ≥15 G hysteresis to prevent chatter near threshold. |
| Output Type | Open-drain - allows flexible pull-up to any logic rail (e.g., 1.8V, 3.3V, 5V) with external RL = 10–100 kΩ. |
| ESD Rating | HBM ±6 kV - robust against handling discharge in high-volume assembly environments. |
| Operating Temperature | -40°C to +85°C - qualified for consumer handheld and industrial enclosure sensing. |
Pinout & Package
AH180-PG-B-S uses SIP-3L (Single In-line Package, 3-pin, straight lead, bulk pack), 2.00 × 1.15 mm body, 0.51 mm nominal height, branded surface active area location aligned with Pin 1 (Vdd).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vdd | Power supply input - must be stabilized with 10–100 nF capacitor per datasheet recommendation. |
| 2 | GND | Ground reference - low-impedance return path required for chopper stabilization integrity. |
| 3 | Output | Open-drain output - sinks current when activated; requires external pull-up resistor (10–100 kΩ). |
Key Features
| Feature | Design Value |
|---|---|
| Omnipolar magnetic response | Switches on with either N- or S-pole - eliminates magnet orientation constraints during assembly. |
| Chopper-stabilized architecture | Reduces offset drift to <1 mV over temperature - maintains consistent Bop/Brp across -40°C to +85°C. |
| Green molding compound (Br/Sb-free) | Complies with EU RoHS Directive 2002/95/EC - no hazardous halogens in package material. |
| Ultra-low power consumption | 24 μW at 3V - enables direct connection to coin-cell or energy-harvesting sources. |
| RF noise immunity | Validated against common-band interference - prevents false triggers in noisy mobile RF environments. |
Applications
| Clam-Shell Phone Cover Detection | Notebook PC Lid Switch |
|---|---|
|
Use Scenario: Detect open/closed state of flip-style mobile phone housing using embedded magnet and PCB-mounted sensor. IC Role / Device Role / Timing Role: Hall-effect switch providing digital lid status signal to baseband processor via GPIO. Use Value: Enables automatic screen on/off and radio sleep/wake without mechanical switches or wear-prone flex cables. |
Use Scenario: Sense laptop lid position to trigger sleep/resume in Windows/Linux OS. IC Role / Device Role / Timing Role: Low-power magnetic switch interfacing directly with EC (Embedded Controller) interrupt pin. Use Value: Reduces system standby current by >100 μA versus alternative reed switches; SIP-3L footprint fits tight hinge zones. |
| PDA Power-On Activation | Smart Remote Buttonless Wake |
|

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 |
|---|---|---|---|
| AL3301QRTT-7 | Higher supply current (45 μA avg), wider Bop range (±25–80 G), DFN2020-3 package only. | Requires tighter board layout control due to smaller 2.0×2.0 mm footprint and no SIP-3L option. | Select when higher magnetic sensitivity tolerance is needed and board space permits DFN. |
| US1881EUA-AAA-000 | Lower ESD rating (HBM ±4 kV), fixed 3.3V-only operation, SC59 package with NC pins. | Lacks 2.5V support and SIP-3L mechanical fit; not suitable for coin-cell or wide-VDD designs. | Choose only if existing SC59 footprint reuse is mandatory and 3.3V rail is guaranteed. |
Compared with AL3301QRTT-7 and US1881EUA-AAA-000, AH180-PG-B-S uniquely combines SIP-3L through-hole compatibility, 2.5V minimum operation, and 24μW power-making it the only choice for cost-sensitive, battery-powered clamshell systems requiring legacy-style leaded assembly.

FAQ
What is the magnetic polarity requirement for AH180-PG-B-S operation?
AH180-PG-B-S is an omnipolar Hall switch: it activates with either a north or south magnetic pole oriented toward its branded surface. No magnet polarity labeling or orientation alignment is required during assembly-reducing manufacturing complexity and enabling use with generic ferrite or NdFeB magnets.
Can AH180-PG-B-S operate from a 2.5V lithium coin cell?
Yes. AH180-PG-B-S is fully specified from 2.5V to 5.5V and draws only 8–24 μA average current at 3V. At 2.5V, supply current remains within datasheet limits, making it suitable for direct connection to CR2032 or BR2032 cells in maintenance-free, multi-year applications like smart remotes or sensor tags.
Is external capacitance required on the Vdd pin?
Yes. The datasheet specifies a 10–100 nF ceramic capacitor between Vdd and GND to stabilize the internal regulator and enhance RF noise immunity. Omitting this capacitor may cause erratic switching or increased susceptibility to EMI in mobile device environments.
Does AH180-PG-B-S have built-in ESD protection?
Yes. AH180-PG-B-S provides HBM ESD protection rated at ±6 kV for SIP-3L and SC59 packages. This level meets IEC 61000-4-2 Level 3 requirements and eliminates need for external TVS diodes in most handheld assembly lines.
