ELMOS: Sensor signal readout IC with SENT interface
E520.33 has been conceived for next generation automotive control devices
With the E520.33, ELMOS introduces a sensor signal readout chip with a SENT
interface. The digital SENT interface enables the chip's use in next
generation automotive control devices. The semiconductor is qualified
according to AEC-Q100 and supports virtually any resistive sensor bridge.
The configurable sensor signal readout electronics provide the following
functions: sensor signal amplification, digital compensation and
linearization for sensor signals, and sensor and self diagnostics.
Configuration and calibration are saved in the integrated EEPROM.
Among other applications, the E520.33 is suited for use in connection with
piezoresistive MEMS, thin and thick film sensors applied to ceramics or
steel, and strain gauges. Measured data may include pressure, strain,
applied load, and torque. Accordingly, the sensor can be used for
processing data supplied by the a/c system or other automotive
applications, such as breaking system, emission control, or tank fill
level/internal pressure.
A programmable amplifier makes input voltages between 3 to 400 mV possible.
In addition, a sensor offset of up to +/-250% full scale (FS) can be
compensated. The E520.33 features a separate temperature measuring channel
with four sensor options: on-chip, bridge resistor, external diode, and
external resistor. Thus all potential sources for temperature measurement
can be integrated and recorded continuously totally independent of pressure
measuring.
The component supports SENT according to SAE J2716 draft rev. 3 and is
supplied as bare die or in a TSSOP20 4.4 package. Samples and evaluation
boards are available.
