Product Overview: AH173-PL-B-B by Diodes Incorporated

The AH173-PL-B-B is a state-of-the-art Hall Effect Latch designed and manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-quality semiconductor products. This device is a key component for modern industrial and consumer applications, where precise and reliable magnetic sensing is critical.

Characterized by its high sensitivity and precision, the AH173-PL-B-B operates as a latch which means it switches output states in response to the presence of a magnetic field, maintaining its state even after the magnet is removed, until a magnetic field of opposite polarity is applied. It is widely used in a variety of applications such as position and speed sensing, brushless DC motor control, and contactless switches.

Key Specifications:

• Supply Voltage: The device operates within a supply voltage range of 3.5V to 20V, making it versatile for use in various circuit configurations.
• Output Type: It offers an open-drain output, which provides the flexibility to connect the output to a voltage level different from the supply voltage, and allows for simple wired-OR configurations.
• Sensing Polarity: The AH173-PL-B-B is sensitive to both north and south poles, providing a bipolar sensing capability.
• High Sensitivity: With its high magnetic sensitivity, the device is capable of detecting weak magnetic fields, making it suitable for a wide range of applications.
• Temperature Range: The operating temperature range of -40°C to 85°C ensures reliable performance across a broad range of environmental conditions.
• Package: It comes in a compact SOT-23 package, which is ideal for space-constrained applications.

The AH173-PL-B-B also features a chopper-stabilized amplifier which minimizes the effects of temperature and voltage variations, ensuring stable operation. Its robust design includes protection against high-voltage transients, reverse power connections, and output short circuits, making it a durable choice for demanding applications.

Whether you're designing a new system or upgrading an existing one, the AH173-PL-B-B from Diodes Incorporated offers the performance and reliability you need for effective magnetic sensing solutions.
