HAL101中文资料Low-Cost Hall-Effect Sensor Family数据手册TDK-Micronas规格书

描述 Description

The HAL 1xy Hall switch family is designed for home appliances and industrial applications. The sensors are produced in CMOS technology and include a temperature-compensated Hall plate with active offset compensation, a comparator, and an open-drain output transistor.
The comparator compares the actual magnetic flux through the Hall plate (Hall voltage) with the fixed reference values (switch ing points). Accordingly, the output transistor is switched on or off.

特性 Features

♦ Temperature ranges
   – C (Commercial, TJ = 0 °C to +85 °C)
   – I (Industrial, TJ = 20 °C to +125 °C)
♦ Operates from 3.8 V to 24 V supply voltage
♦ Operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
♦ Overvoltage protection at all pins
♦ Reverse-voltage protection at VDD pin
♦ Magnetic characteristics are robust against mechanical stress effects
♦ Short-circuit protected open-drain output by thermal shut down
♦ Constant switching points over a wide supply voltage and temperature range
♦ The decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics
♦ High temperature stability for home appliances and industrial applications
♦ High ESD ratingMajor Applications
