A3213ELHLT-T Typical application Circuitry

A3213ELHLT-T

The A3213ELHLT-T is part of Allegro Microsystems' A3213 series, a family of ultra-sensitive, pole-independent Hall-effect switches with latched digital output. These devices are specifically designed for battery-operated, mobile, or wireless applications where power efficiency and sensitivity to magnetic fields are critical. The A3213 series is notable for its chopper-stabilized Hall element, which minimizes the impact of temperature variations and stress on the output, ensuring reliable operation across a wide range of environmental conditions. The "ELHLT-T" designation indicates that this device is provided in a small, low-profile surface-mount package (SOT-23W) and is available in tape and reel packaging for automated assembly processes.

1. Power Supply Voltage (VCC Pin): The A3213ELHLT-T operates with a supply voltage ranging from 2.4 volts to 5.5 volts, making it compatible with a wide variety of low-power digital systems, including those that operate at logic levels of 3.3V and 5V. The VCC pin should be connected to the positive supply voltage, with a bypass capacitor placed close to the pin to filter out noise and provide a stable voltage source.

2. Ground Connection (GND Pin): The GND pin serves as the ground reference for the device. A solid connection to the system ground is essential for the accurate sensing of magnetic fields and stable operation of the Hall-effect switch. Ensuring a low-resistance path to ground helps minimize potential errors in magnetic detection caused by ground noise.

3. Output (OUT Pin): The OUT pin provides a digital output signal that indicates the magnetic field's presence exceeding the device's programmed operate point. This latched output remains in its present state until the magnetic field polarity opposite to the one that triggered it is detected, making the device particularly useful in applications requiring detection of magnetic field presence or absence without continuous monitoring. The output can be directly interfaced with microcontrollers or other logic devices to trigger actions based on magnetic field changes.

4. Bypass Capacitor (Connected to VCC and GND): Although not a pin, it's crucial to connect a bypass capacitor (typically 0.1 µF) between the VCC and GND pins as close to the device as possible. This capacitor helps stabilize the power supply line, suppresses high-frequency noise, and ensures that the A3213ELHLT-T operates reliably, especially in environments with electrical noise.

The A3213ELHLT-T's design focuses on simplicity and efficiency, making it ideal for portable and wireless applications where power consumption and sensitivity are paramount. Its wide operating voltage range and pole-independent latch feature allow for versatile use in various applications, including open/closed detection in consumer electronics, position sensing in industrial equipment, and proximity detection in battery-powered devices. When designing circuits with the A3213ELHLT-T, attention to power supply quality, grounding practices, and magnetic field orientation relative to the device will ensure optimal performance and reliable magnetic field detection.
