RBicdLite-AutoTM Sensor Signal
Conditioner with Diagnostics
ZSSC3015
Datasheet
Brief Description
The ZSSC3015 sensor signal conditioner IC is
adjustable to nearly all piezo-resistive bridge
sensors. Measured and corrected bridge values are
provided at the Sig™ pin, which can be configured
as an analog voltage output or as a one-wire serial
digital output.
The ZACwire™ digital one-wire interface (OWI) can
be used for a simple PC-controlled calibration
procedure to program a set of calibration coefficients
into an on-chip EEPROM. The calibrated ZSSC3015
and a specific sensor are mated digitally: fast,
precise, and without the cost overhead associated
with trimming by external devices or laser. Integrated
diagnostics functions make the ZSSC3015 parti-
cularly well suited for automotive applications.
Features
• Digital compensation of sensor offset, sensitivity,
temperature drift, and nonlinearity
• Programmable analog gain and digital gain;
accommodates bridges with spans < 1mV/V
and high offset
• Many diagnostic features on chip (e.g., EEPROM
signature, bridge connection checks, bridge short
detection, power loss detection)
• Independently programmable high and low
clipping levels
• 24-bit customer ID field for module traceability
• Internal temperature compensation reference (no
external components)
• Option for external temperature compensation
with addition of single diode
• Output options: rail-to-rail ratiometric analog
voltage (12-bit resolution), absolute analog
voltage, ZACwire™ digital one-wire interface
• Fast power-up to data out response; output
available 5ms after power-up
• Current consumption depends on programmed
sample rate and mode: 1mA down to 300µA (typ.)
• Fast response time: 1.4ms typical
• High voltage protection: ≤ 30V with external JFET
• AEC-Q100 qualified
