AH377 and AH378 Hall Effect Latch IC's

Diodes' AH377 and AH378 Hall-effect latch IC's operate at voltages of 3 V to 28 V over the extended temperatures range of -40°C to +125°C

Image of Diodes AH377 and AH378 Latch IC'sDiodes' AH377x and AH378x product range is specifically designed for commutation of brushless DC motors, flow meters, linear encoders, and position sensors in industrial, consumer, home appliance, and personal care applications. Offering 5 high-tolerance sensitivity band options ranging from a typical 25 to 140 Gauss, and options of open-drain or internal pull-up outputs, the product family can be used in multiple applications. To enhance system reliability, the family is specified over the whole operating range of 3 V to 28 V and -40°C to +125°C. It features VDD and output Zener clamps, current limit, and an ESD rating of 6 kV. Open-drain output for pull-up flexibility or internal pull-up for higher levels of integration. All the products are available in industry-standard SOT23 and SIP-3, and selected products in SC59.

Features and Benefits
