Product details
Overview
ZSSC4169DE5T-APC from Renesas Electronics 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 accuracy over −40°C to +150°C, and supports both internal PTAT and external diode temperature references for full-sensor compensation in brake pressure and hydraulic systems.
For engineers reviewing the ZSSC4169DE5T-APC datasheet, ZSSC4169DE5T-APC pinout, ZSSC4169DE5T-APC application, or ZSSC4169DE5T-APC equivalent, key selection criteria include SENT v3.0 Fast/SDM channel support, AEC-Q100 Grade 0 qualification, 16-TSSOP wettable-flank package, one-pass end-of-line calibration, and integrated 16-bit RISC microcontroller for digital nonlinearity correction.
Technical Context
The ZSSC4169DE5T-APC implements a fully digital signal path: a programmable gain amplifier (PGA) with up to 200× analog gain feeds a 14-bit ADC; offset, gain, sensitivity, temperature drift, and nonlinearity are corrected via on-chip 16-bit RISC MCU executing stored calibration coefficients. Temperature compensation uses either internal PTAT junction or external diode sensing.
Digital output is delivered exclusively through a single-pin SENT interface compliant with SAE J2716 Rev. 3.0, supporting simultaneous transmission of primary sensor data (Fast Channel) and supplementary diagnostics or ID (Serial Data Message Channel), plus One-Wire Interface (OWI) for end-of-line calibration-all without external trimming components.

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. | Targeted at magnetic position sensing-not resistive bridge pressure sensing-requiring different sensor topology and ECU interface. | Select only for Hall-based rotary/linear position systems; not a functional substitute for ZSSC4169DE5T-APC in bridge sensor applications. |
| Infineon DPS310 | Integrated MEMS pressure sensor with I²C/SPI output; includes on-die temperature compensation but no external bridge input or SENT support. | Self-contained absolute pressure sensor; lacks configurable bridge input, PGA, or SENT protocol-unsuitable for custom strain-gauge or piezoresistive bridges. | Choose when using monolithic MEMS pressure die; not applicable where external bridge sensors and SENT bus integration are mandatory. |
Compared with MLX90393 and DPS310, the ZSSC4169DE5T-APC uniquely combines configurable bridge input, 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 bridge sensing in automotive safety-critical pressure systems.

FAQ
What is the SENT interface configuration supported by the ZSSC4169DE5T-APC?
The ZSSC4169DE5T-APC implements SAE J2716 Revision 3.0 SENT with dual-channel capability: Fast Channel transmits primary sensor data (e.g., pressure) with 12-bit resolution, while Serial Data Message (SDM) Channel carries supplementary information such as diagnostics, device ID, or status flags-all on a single SENT output pin. The ZSSC4169DE5T-APC also uses this pin for One-Wire Interface calibration.
Does the ZSSC4169DE5T-APC support external temperature sensing?
Yes, the ZSSC4169DE5T-APC supports both internal PTAT junction and external diode temperature sensing via dedicated TS1 and TS2 pins. This enables dual-point temperature compensation for improved accuracy across wide thermal ranges, especially critical in under-hood automotive applications where ambient and sensor self-heating vary significantly.
What is the maximum bridge input sensitivity the ZSSC4169DE5T-APC can handle?
The ZSSC4169DE5T-APC accepts bridge input spans from 1 mV/V to 800 mV/V, adjustable via its programmable gain amplifier (PGA) with up to 200× analog gain. This wide dynamic range allows direct interfacing with low-output strain gauges and high-output piezoresistive elements without external amplification or attenuation circuitry.
Is the ZSSC4169DE5T-APC qualified for automotive safety applications?
Yes, the ZSSC4169DE5T-APC is qualified per AEC-Q100 Grade 0 (−40°C to +150°C) and explicitly supports ASIL C safety applications. Its integrated diagnostics, NVM integrity checking, SENT message CRC, and robust EMC performance meet functional safety requirements for pressure sensing in braking, steering, and suspension systems.
What package type does the ZSSC4169DE5T-APC use, and why is it significant?
The ZSSC4169DE5T-APC uses a 16-TSSOP package (4.4 mm × 5.0 mm) with exposed thermal pad and wettable flanks. This package enables reliable thermal dissipation in high-temperature automotive environments and supports automated optical inspection (AOI) of solder joints-critical for zero-defect manufacturing in safety-critical automotive electronics.
