HAR 3920-2100 (dual-chip) is a Hall effect position sensor with a stable compensation capability and equipped with the ratio simulation output and switch output
This sensor has been defined as ASIL C -level, which can be integrated into the car safety -related system, which can reach the ASIL D level
The target car application scenarios include throttle or brake pedal location detection, clutch position determination, non -contact potentiometer or throttle valve position measurement **
TDK Co., Ltd. (TSE: 6762) uses a new dual-chip sensor HAR 3920-2100*for new application scenarios for automotive and industrial application scenarios, further expanding the Micronas 3D HAL position sensor series.Its design aims to meet the demand for high -precision measurement of linear positions and angle positions when there is interference in the mixed field.According to the ISO 26262 standard, the HAR 3920 meets the ASIL C -Class requirements and is suitable for a car safety -related system that integrates the ASIL D -class.This sensor is suitable for application scenarios such as the location of the throttle pedal or the position of the throttle valve, or the non -contact potentiometer and other application scenarios.** It is planned to be put into production in April 2024; samples can now be required.
HAR 3920 stands out with its dual redundant design, that is, two independent chips are stacked in a single packaging and the electrical connection is connected to one side pin.This stacking chip structure ensures consistent output signal characteristics by occupying the same magnetic field position.The sensor uses Hall technology to measure vertical and horizontal magnetic field components, and uses Hall board array to inhibit external mixed fields.The sensor can measure the range range and linear motion of the magnetic 360 ° angle.A simple dual -pole magnet is sufficient to measure the rotation angle. Ideally, it can be placed above the sensitive area in the shaft configuration.The sensor also supports the steady -axis measurement of the messy field.
HAR 3920 has a linear, ratio simulation output signal, and a passive disconnection detection function, which can be compatible with pull -up resistance or drop -down resistance, with a wide range of uses.In addition, it also provides switching output (leak opening road), which is derived from calculating location information or other sources on the equipment signal path, supporting users to define the opening/level, switching logic, and switching polarity.
The signal processing on the film can calculate the angle of each chip according to the magnetic field component, and convert the value to an analog output signal.Users can adjust the main characteristics of gain, offset, and reference position by programming the non -prone dislocated memory.
This sensor is designed for automotive and industrial application scenarios. It can work within the environmental temperature range of -40 ° C to 160 ° C, depending on the range of power supply voltage.This sensor is very compact and widely used, and it provides a sixteen -needle SSOP16 SMD packaging.
