Features
With the introduction of the TLE4998x
product family, Infineon offers an extensive product portfolio of Linear Hall
sensors for automotive and industrial
systems. The TLE4998x is based on a
similar concept as the TLE4997. The
analog interface implemented in the
TLE4997 is replaced by a selection of
digital output protocols. The interface
options of the TLE4998x include Pulse
Width Modulation (PWM), Single Edge
Nibble Transmission (SENT) as well as
Short PWM Codes (SPC). The sensor is
conveniently programmable in EEPROM
and is available in three different leaded
packages. With its temperature and
stress compensation features, it provides outstanding performance stability
over both temperature and lifetime.
