Honeywell is pleased to announce its High Sensitivity Digital Latching Sensor ICs, VF360NT and VF360ST, that are AEC-Q100 qualified for use in the transportation industry.
The VF360NT and VF360ST High Sensitivity Latching Digital Hall-Effect Sensor ICs are small, sensitive and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles. The VF360NT is turned ON by a North pole, while the VF360ST is turned ON by a South pole. This sensor IC does not use chopper stabilization on the Hall element, providing a clean output signal and a faster latch response time when compared to competitive high sensitivity Hall-effect bipolar latching sensor ICs which do use chopper stabilization.
VALUE TO CUSTOMERS
