Diodes Incorporated AH3360-Z-7

Overview

AH3360-Z-7 from Diodes Incorporated is a high-sensitivity, micropower unipolar Hall-effect switch IC in SOT553 package, operating from 1.6V to 3.6V supply with 4.3µA average current at 1.85V. It activates on south-pole magnetic field exposure (BOP = 30 G typ), outputs open-drain low-state (VOL = 0.2 V @ 1mA), 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-Z-7 datasheet, AH3360-Z-7 pinout, AH3360-Z-7 application, or AH3360-Z-7 equivalent, this page delivers verified functional identity, validated SOT553 pin mapping, confirmed magnetic switching thresholds (BOP/BRP), real-world power consumption data (IDD(AVG) = 4.3 µA), and direct alternative part comparisons grounded in Diodes' official documentation.

Technical Context

The AH3360-Z-7 implements a chopper-stabilized Hall sensor with integrated sleep/awake logic and latch-based output driver. Its hibernating clocking system cycles between 50 µs awake periods and ~100 ms sleep intervals, achieving sub-5 µA average current while maintaining valid output sampling after two full cycles (~100 ms).

It operates unipolar mode exclusively: activation requires south pole applied to the marking side, with BOP = 30 G (typ) and BRP = 20 G (typ) at +25°C, yielding 10 G hysteresis (BHY) - all specified across –40°C to +85°C and stable over 1.6–3.6 V supply range without external pull-up resistors.

FAQ

What is the magnetic polarity requirement for AH3360-Z-7 activation?

The AH3360-Z-7 activates exclusively with a south pole applied to the marking side of the package. Its unipolar architecture does not respond to north poles, and reverse-field exposure yields no output change. This behavior is fixed by internal Hall plate orientation and cannot be inverted via external configuration.

Can AH3360-Z-7 operate without an external decoupling capacitor?

No - a 100 nF ceramic capacitor is required between VDD and GND, placed as close as possible to pins 1 and 4. This stabilizes the internal hibernating clock and suppresses noise-induced false triggering, especially in RF-rich environments like cellular handsets. Omission risks erratic output transitions and increased IDD(AVG).

Is the NC pin on AH3360-Z-7 electrically isolated or internally tied?

Pin 2 and Pin 3 of the SOT553 package are true no-connect (NC) terminals - they have no internal bond wire or silicon connection. These pins may be left floating or connected to GND for mechanical reinforcement, but neither action affects electrical performance or thermal behavior.

How does the hibernating clock affect system-level timing in lid-detect applications?

The hibernating clock imposes a maximum 100 ms delay between magnetic field application and valid output assertion - because the device samples only once per ~100 ms period, and output becomes stable after the second cycle. For applications requiring faster response, the device must be held in awake state via periodic VDD toggling, increasing average current to 2.1 mA.
