Honeywell (VF360NT & VF360ST) High Sensitivity Latching Digital Hall-effect Sensor ICs

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
*  AEC-Q100 qualification provides enhanced reliability and quality of electronic components. Components meeting these specifications are often suitable for use in harsh automotive environments without the customer’s need for additional component-level qualification testing.
*  Designed to provide reliable, consistent performance and a fast response time, enhancing efficiency in brushless dc motor (BLDC) applications
*  Designed to provide a wide supply voltage range and no chopper delay, allowing for potential use in a variety of applications
*  Designed to provide a clean output signal without the customer having to include additional circuitry to achieve noise suppression due to chopper stabilization

FEATURES
*  Qualified to the AEC-Q100 standard for potential use in automotive applications
*  Fastest response time in its class [1.5 μs]
*  Operate from 30 Gauss typical at 25°C [77 °F] and 55 Gauss maximum over the full -40 °C to 150 °C [-40 °F to 302 °F] temperature range
*  Latching magnetics
*  Repeatable magnetics (no jitter)
