Product details
Overview
ZSSC4169DE5R-APC from Renesas is an automotive-grade resistive sensor signal conditioner IC with SENT digital output, designed for high-accuracy conditioning of differential bridge sensors. It delivers 14-bit ADC resolution, ±0.5% FS total error over −40°C to +150°C, and supports both internal PTAT and external diode temperature references in hydraulic brake pressure sensing systems.
For engineers reviewing the ZSSC4169DE5R-APC datasheet, ZSSC4169DE5R-APC pinout, ZSSC4169DE5R-APC application, or ZSSC4169DE5R-APC equivalent, key selection criteria include SENT v3.0 Fast/SDM channel support, AEC-Q100 Grade 0 qualification, 16-TSSOP wettable-flank package, and one-pass end-of-line calibration via OWI on DOUT.
Technical Context
The ZSSC4169DE5R-APC integrates a programmable gain amplifier (PGA) with up to 200× analog pre-amplification, a 14-bit sigma-delta ADC for bridge input, and a 16-bit RISC microcontroller for real-time digital compensation of offset, gain, sensitivity, temperature drift, and nonlinearity. Its signal path supports full-bridge and half-bridge configurations with selectable internal or external temperature sensing.
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 including product 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 front-end with I²C output; no SENT interface; 16-bit resolution but no built-in bridge PGA | Targets magnetic position sensing, not resistive pressure bridges; lacks automotive SENT compliance and ASIL C support | Select only for Hall-based rotary/linear position sensing where SENT is not required |
| Infineon DPS310 | Barometric pressure sensor with integrated MEMS element and I²C/SPI output; no external bridge interface or PGA | Fixed-function pressure sensor IC, not a configurable signal conditioner; unsuitable for custom bridge designs or hydraulic fluid media | Choose only for ambient air pressure measurement; not a functional substitute for ZSSC4169DE5R-APC's bridge conditioning capability |
Compared with MLX90393 and DPS310, the ZSSC4169DE5R-APC uniquely combines programmable bridge amplification, 14-bit ADC, SENT v3.0 output, and AEC-Q100 Grade 0 qualification-making it the only option among the three that supports end-of-line calibrated resistive pressure sensing in safety-critical automotive hydraulic systems.

FAQ
What is the SENT interface configuration supported by ZSSC4169DE5R-APC?
The ZSSC4169DE5R-APC implements SAE J2716 Revision 3.0 SENT with both Fast Channel (for primary sensor data) and Serial Data Message (SDM) Channel (for supplementary data like temperature, diagnostics, or product ID) on a single DOUT pin. It does not support PWM or UART interfaces. The SENT frame structure is fixed per calibration configuration and cannot be user-reprogrammed in-field.
Does ZSSC4169DE5R-APC support external temperature sensing only, or both internal and external?
ZSSC4169DE5R-APC supports both internal PTAT junction temperature sensing and external diode-based temperature measurement via TS1/TS2 pins. The device allows selection between internal or external reference-or simultaneous use-for dual-point thermal compensation of bridge output and sensor self-heating effects.
What is the maximum bridge excitation voltage compatible with ZSSC4169DE5R-APC?
ZSSC4169DE5R-APC does not provide bridge excitation voltage; it conditions differential bridge outputs. Excitation must be supplied externally-typically 5 V or 10 V-with bridge output span ranging from 1 mV/V to 800 mV/V. The input stage accepts up to ±1.25 V differential common-mode range, limiting max excitation based on sensor sensitivity and gain setting.
Is ZSSC4169DE5R-APC pin-compatible with other variants in the ZSSC4169 family?
No, ZSSC4169DE5R-APC (16-TSSOP) is not pin-compatible with ZSSC4169DE4R (24-QFN). Pin counts, layouts, and thermal pad configurations differ significantly. Migration requires PCB redesign. However, register maps, SENT protocol, and calibration methodology are identical across all ZSSC4169D variants, enabling firmware reuse.
How is calibration performed for ZSSC4169DE5R-APC, and what equipment is needed?
Calibration for ZSSC4169DE5R-APC is performed end-of-line using the One-Wire Interface (OWI) via the DOUT pin. Renesas-provided evaluation kit (ZSSC4169EVKV1P4) and PC-based calibration software are required. The process executes a single-pass algorithm measuring offset, gain, and temperature coefficients across defined pressure/temperature points, writing results directly to on-chip NVM without external trim components.
