They are designed to input flap to engine, convertible roof position, electronic respond to alternating North and South poles. The VF360NT parking brakes, electronic window lifts and anti-pinch is turned ON by a North pole, while the VF360ST and VF460S power window systems, HVAC blowers, headlights, power are turned ON by a South pole. This sensor IC does not use doors, mirrors and tail gates, seat motors, steering, chopper stabilization on the Hall element, providing a clean windshield washers and wipers output signal and a faster latch response time when compared Speed and RPM sensing: Motors and fans tachometer and to competitive high sensitivity Hall-effect latching sensor ICs counter pickup which do use chopper stabilization. Flow rate sensing VALUE TO CUSTOMERS PORTFOLIO AEC-Q100 qualification provides enhanced reliability and The VF360NT, VF360ST, and VF460S are a part of quality of electronic components. Components meeting Honeywells family of latching digital Hall-effect sensor ICs these specifications are often suitable for use in harsh which also include: automotive environments without the customers need for SS360NT, SS360ST, SS360ST-10K, SS460S, SS460S-T2. additional component-level qualification testing. SS460S-LP Designed to provide reliable, consistent performance and SS360PT, SS460P, SS460P-T2 a fast response time, enhancing efficiency in brushless dc SS361CT, SS461C motor (BLDC) applications SS361RT, SS461R Designed to provide a wide supply voltage range and no SS400 Series, SS500 (select catalog listings) chopper delay, allowing for potential use in a variety of VF526DT (dual outputs) applications Designed to provide a clean output signal without the customer having to include additional circuitry to achieve noise suppression due to chopper stabilization DIFFERENTIATION Honeywells VF360NT, VF360ST, and VF460S AEC-Q100- qualified latching sensor ICs offer better performance than many competitive sensor ICs that employ chopper stabilization techniques. Response time: Honeywells device provides a fast response time, enabling efficiency in BLDC motors. No noise generation: Honeywells device utilizes a resistor- capacitor (RC) circuit to enable noise suppression required for chopper stabilized sensors.
