Omnipolar Hall sensor AH3663 (Latch Type)

Product catalog summary

Features and Benefits
The AH3663 is a digital micropower omnipolar Hall IC designed for various applications including automotive, consumer, and industrial electronics. It offers a digital output with an omnipolar latch, stable performance across a temperature range of -40°C to 85°C, and operates on a low voltage range of 2.5V to 5.5V. The device is resistant to mechanical stress and provides a non-contact output, ensuring safety and reliability. It is available in TO-92UA and SOT-23-3L package options and complies with EU RoHS and REACH standards.

Application Examples
The AH3663 is suitable for applications such as water flow sensing, liquid level detection, position sensing, handheld equipment (e.g., cellphones, notebooks), contactless keys/buttons, Bluetooth headsets, and door latch systems.

Selection Guide
The AH3663 is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). The SOT-23-3L is a surface mount package, while the TO-92UA is a through-hole package. Both types operate within a temperature range of -40°C to 85°C.

General Description
The AH3663 integrates several components on a single silicon chip, including a reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger, and open-drain output driver. It is manufactured using CMOS technology, requiring lower supply voltage and power.

Electrical and Magnetic Operating Characteristics
The device operates with a supply voltage range of 2.5V to 5.5V and features a high-level output voltage of 3.3V. It has a low-level output voltage of 0.3V and an awake supply current of 6.0 µA. The magnetic operating characteristics include a south operating point of 1.0 mT and a north operating point of -1.0 mT, with hysteresis ensuring stable switch status.

Absolute Maximum Ratings
The AH3663 can handle a supply voltage of up to 5V, an output current of 1 mA, and operates within a temperature range of -40°C to 85°C. The maximum junction temperature is 165°C, and it has an ESD sensitivity of 2 kV according to the AEC-Q100-002 standard.

Magnetic Behavior
The sensor outputs a low level when a magnet is close (|B|≥|BOP|) and a high level when the magnet is far (|B|≤|BRP|). The steady hysteresis ensures stable switching.

Package Information
The AH3663 is available in SOT-23-3L and TO-92UA packages, with detailed dimensions provided for each type.

Marking Information
The package forms include M (SOT-23-3L), S (SOT-89), and UA (TO-92UA/TO-92S). Operating temperature options are E (-40℃ to +85℃) and L (-40℃ to +150℃).

Digital Micropower Omnipolar Hall IC Low Average Power Internal timing circuit activates the IC for 45 µs and deactivates it for the remainder of the period (45 ms). A short "awake" time allows for stabilization prior to the sampling and data latching on the falling edge of the timing pulse. The output during the "sleep" time is latched in the last sampled state. The supply current is not affected by the output state. IAWK Period Sleep Period Nanjing AH Electronic Science & Technology Co., Ltd.
