High Sensitivity Latching Hall-effect Digital Sensor ICs: VF360NT, VF360ST, VF460S 32311084 Issue D Datasheet DESCRIPTION The VF360NT, VF360ST, and VF460S 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 and VF460S are 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 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 DIFFERENTIATION Honeywell’s VF360NT, VF360ST, and VF460S AEC-Q100qualified latching sensor ICs offer better performance than many competitive sensor ICs that employ chopper stabilization techniques. • Response time: Honeywell’s device provides a fast response time, enabling efficiency in BLDC motors. • No noise generation: Honeywell’s device utilizes a resistorcapacitor (RC) circuit to enable noise suppression required for chopper stabilized sensors.

PCB wave soldering: 250°C to 260°C [482°F to 500°F] for 3 s max. NOTICE These Hall-effect sensor ICs may have an initial output in either the ON or OFF state if powered up with an applied magnetic field in the differential zone (applied magnetic field >Brp and <Bop). Honeywell recommends allowing 10 µs after supply voltage has reached 5 V (VF360NT, VF360ST) or 3 V (VF460S) for the output voltage to stabilize. CAUTION NOTICE The magnetic field strength (Gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified limits, the switch must be placed in a uniform magnetic field.
