Product details
Overview
ZSSC4169DE5R from Renesas Electronics is an automotive-grade resistive sensor signal conditioner IC with SENT digital output, designed for precision conditioning of single-bridge sensors in harsh environments. It delivers 14-bit bridge ADC resolution, ±0.5% FS accuracy over −40°C to +150°C, and supports both internal PTAT and external diode temperature references for dual-sensor compensation in brake pressure systems.
For engineers reviewing the ZSSC4169DE5R datasheet, ZSSC4169DE5R pinout, ZSSC4169DE5R application, or ZSSC4169DE5R equivalent, key selection criteria include SENT v3.0 Fast/SDM channel support, AEC-Q100 Grade 0 qualification, 16-TSSOP wettable-flank package (ENG16), one-pass end-of-line calibration via OWI, and integrated diagnostics for ASIL C–compliant safety systems.
Technical Context
The ZSSC4169DE5R implements a 16-bit RISC microcontroller for real-time digital compensation of offset, gain, sensitivity temperature drift, and 3rd-order nonlinearity across its operating range. Its analog front-end includes a programmable gain amplifier (PGA) with up to 200× gain and supports bridge input spans from 1 mV/V to 800 mV/V.
Digital output is delivered exclusively via a single-pin SENT interface compliant with SAE J2716 Rev. 3.0, using Fast Channel for primary sensor data and Serial Data Message (SDM) Channel for supplementary values (e.g., temperature, ID). Calibration coefficients and configuration are stored in on-chip NVM qualified for automotive life-cycle reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar resistive bridge signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis MLX90393 | Tri-axis Hall sensor frontend with I²C output; no SENT interface or bridge input capability | Targeted at position/magnetic sensing, not pressure/strain bridge conditioning | Select only for magnetic field measurement; incompatible for ZSSC4169DE5R's bridge + SENT use case |
| Infineon DPS310 | Integrated barometric pressure sensor with I²C/SPI; no external bridge interface or programmable gain | Fixed MEMS transducer with factory-calibrated output; no support for user-defined resistive bridges | Choose when measuring absolute atmospheric pressure; not a functional substitute for configurable bridge signal conditioning |
Compared with MLX90393 and DPS310, the ZSSC4169DE5R uniquely combines programmable bridge amplification, dual-temperature compensation, SENT v3.0 output, and AEC-Q100 Grade 0 qualification-making it the only option among the three capable of replacing legacy analog pressure transmitters in ASIL C–rated brake and steering subsystems.

FAQ
What is the operating temperature range specified for the ZSSC4169DE5R?
The ZSSC4169DE5R is rated for continuous operation from −40°C to +150°C ambient temperature. This Grade 0 specification is validated per AEC-Q100 and enables direct placement in high-heat zones such as brake calipers, power steering gear housings, and air suspension compressors-without derating or external cooling. The ZSSC4169DE5R maintains ±0.5% FS accuracy across this full range.
Does the ZSSC4169DE5R support both internal and external temperature sensing simultaneously?
Yes, the ZSSC4169DE5R supports concurrent internal PTAT and external diode temperature measurements via dedicated TS1 and TS2 inputs. This dual-path architecture allows independent compensation of bridge sensor drift and output temperature reporting-critical for applications like hydraulic steering where oil temperature must be monitored separately from sensor die temperature. The ZSSC4169DE5R processes both signals within its 16-bit RISC core.
What SENT protocol version does the ZSSC4169DE5R implement?
The ZSSC4169DE5R implements SAE J2716 Revision 3.0 SENT protocol, supporting both Fast Channel (for primary sensor data) and Serial Data Message (SDM) Channel (for secondary values like temperature or device ID) on a single SENT pin. It does not support earlier revisions or proprietary SENT variants. The ZSSC4169DE5R's SENT output is fully interoperable with standard automotive ECUs compliant with J2716 Rev. 3.0.
Is external circuitry required for calibration of the ZSSC4169DE5R?
No external trimming components or laser calibration equipment are required. The ZSSC4169DE5R performs one-pass, end-of-line calibration via its SENT pin acting as a One-Wire Interface (OWI), enabling digital coefficient programming directly into on-chip NVM. This eliminates manual potentiometer adjustments or post-solder trimming-reducing production cost and improving repeatability. The ZSSC4169DE5R stores all calibration data internally.
What package type and footprint does the ZSSC4169DE5R use?
The ZSSC4169DE5R uses a 16-pin TSSOP package measuring 4.4 mm × 5.0 mm with an exposed thermal pad (ENG16 footprint), rated MSL1 and featuring wettable flanks for automated optical inspection. It is distinct from the 24-QFN variant (ZSSC4169DE4R) and requires a dedicated land pattern per Renesas' AN-932 layout guidelines. The ZSSC4169DE5R's TSSOP form factor simplifies hand-soldering and rework in low-volume prototyping.
