Diodes Incorporated AH183-PG-A

Overview

AH183-PG-A from Diodes Incorporated is a micropower, bipolar-operated Hall-effect switch in SIP-3L package, designed for battery-powered handheld devices. It features 2.5–5.5V operation, 280–500 µA average supply current, 40–60 Gauss south-pole activation (brand-side), and 10–30 Gauss release point, enabling low-power cover detection and position sensing in portable electronics.

For engineers reviewing the AH183-PG-A datasheet, AH183-PG-A pinout, AH183-PG-A application, or AH183-PG-A equivalent, key selection criteria include magnetic sensitivity polarity (SIP-3L requires south-pole actuation), ultra-low quiescent current, thermal stability across –40°C to +85°C, and RoHS-compliant "Green" packaging with lead-free finish.

Technical Context

The AH183-PG-A integrates a Hall plate, chopper-stabilized amplifier, offset-canceling circuitry, and open-drain NMOS output driver. Its internal architecture enables stable switching despite mechanical stress and temperature drift, with hysteresis (Bhy ≥10 Gauss) preventing chatter near threshold.

Unlike the AH182, the AH183 operates at higher average current (280–500 µA vs. 5–10 µA) and longer period (200–400 ms vs. 50–100 ms), trading power efficiency for improved noise immunity and response consistency in dynamic magnetic environments.

Key Specifications

Pinout & Package

AH183-PG-A uses the SIP-3L (Single In-line Package, 3-lead) with gull-wing leads, 2.00 mm × 1.15 mm footprint, and branded top surface indicating active side orientation.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar Hall-effect switch applications.

Compared with AL33030Q-13 and TLE4913-2D, the AH183-PG-A delivers optimal size-power trade-off for consumer portables: its SIP-3L package fits sub-3 mm height constraints, and its 280–500 µA current enables multi-year battery life where alternatives draw 10–40× more power or require layout changes.

Availability

AH183-PG-A is available at Aetrix Electronics and suitable for cover detection, speed measurement, home safety sensors, and portable device position sensing requiring stable component supply and long-lifecycle support.

Supply support for AH183-PG-A includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What magnetic polarity activates the AH183-PG-A in SIP-3L package?

The AH183-PG-A in SIP-3L package is activated by the south pole of a magnet applied to the branded (marked) side of the package. This polarity requirement is fixed per package type and cannot be reversed via configuration. North-pole activation applies only to the SC59 variant.

Can AH183-PG-A drive an LED directly without a current-limiting resistor?

No. The AH183-PG-A has an open-drain NMOS output rated for 10 mA sink current, but it lacks internal current limiting. A series resistor (e.g., 1 kΩ for 3.3 V supply) must be used between Vdd and the LED anode to prevent excessive current and ensure reliable switching.

Is AH183-PG-A qualified for automotive applications per AEC-Q100?

No. AH183-PG-A is not AEC-Q100 qualified. Diodes Incorporated explicitly states that automotive-grade variants require separate qualification (e.g., PPAP capability, IATF 16949 manufacturing), and this part is designated for consumer/handheld use only per DS31024 Rev. 10.

How does AH183 differ from AH182 in practical circuit design?

The AH183 draws 280–500 µA average current versus AH182's 5–10 µA, resulting in ~50× higher power consumption but offering longer period (200–400 ms vs. 50–100 ms) and improved noise rejection. Designers selecting AH183 accept higher current for greater magnetic stability in electrically noisy environments.
