888K汽车传感器HAL888K原装进口
The HAL888 is a new member of the Micronas family
of programmable linear Hall sensors. It is designed to
fulfill the requirements of today’s state-of-the-art appli-
cations for linear and angular measurements that
require programmability to compensate system toler-
ances.
Features
– programmable linear Hall effect sensor with ratio-
metric output and digital signal processing
– 12-bit analog output
– multiple programmable magnetic characteristics in a
non-volatile memory (EEPROM) with redundancy
and lock function
– open-circuit (ground and supply line break detec-
tion) with 10 k? pull-up and pull-down resistor,
overvoltage and undervoltage detection
– for programming an individual sensor within several
sensors in parallel to the same supply voltage, a
selection can be done via the output pin
– temperature characteristics are programmable for
matching common magnetic materials
– programmable clamping function
– programming through a modulation of the supply
voltage
– operates from ?40 °C up to 140 °C junction temper-
ature
– operates from 4.5 V up to 5.5 V supply voltage in
specification and functions up to 8.5 V
– operates with static magnetic fields and dynamic
magnetic fields up to 1 kHz
– overvoltage and reverse-voltage protection at all
pins
– short-circuit protected push-pull output
– EMC and ESD optimized design
