ZSSC4151CE5T

Overview

The ZSSC4151CE5T is a CMOS sensor signal conditioner manufactured by Renesas Electronics, designed for resistive bridge sensors. It operates on a single supply voltage ranging from 4.5 V to 5.5 V with a maximum operating current of 7 mA. The device features an internal 16-bit RISC microcontroller that executes calibration algorithms to digitally compensate for sensor offset, sensitivity, temperature drift, and nonlinearity. These coefficients are stored in integrated EEPROM. It provides an analog output and supports digital communication via I2C or ZACwire interfaces. The component is housed in a 16-pin TSSOP package (5.0 x 4.4 mm) and is qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Digital compensation for sensor offset, sensitivity, temperature drift, and nonlinearity using an internal 16-bit RISC microcontroller
• High-voltage tolerant pins (VDDE, VSSE, AOUT) capable of withstanding up to 40V with reverse polarity protection
• Configurable analog gain up to 200 times with ratiometric voltage output options
• Dual interface support for analog output and digital control via I2C or ZACwire protocols

Applications

• Automotive pressure sensors
• Automotive temperature sensors
• Industrial load cells
• Force measurement systems

Procurement Notes

Verify the specific suffix CE5T against the official Renesas datasheet to confirm the TSSOP-16 packaging and tape-and-reel availability. Ensure the order matches the exact part number as suffixes define package type and shipping quantity. Confirm RoHS compliance status and AEC-Q100 qualification requirements prior to procurement.

Selection Notes

Select this component when interfacing with resistive bridge sensors requiring high precision and digital calibration capabilities. The ZSSC4151CE5T is suitable for designs needing a 5V supply and I2C connectivity. Consider the 16-TSSOP package dimensions for PCB layout constraints. Verify that the required gain range and output resolution meet the specific sensor application needs.

Part Context

The ZSSC4151 belongs to the ZSSC4151 family of sensor signal conditioners. Other variants include die forms (AE1C), QFN packages (CE4R), and different reel configurations (CE6R). This specific model represents the surface-mount TSSOP version intended for automated assembly processes in automotive and industrial electronics manufacturing.

Replacement Considerations

Direct replacements within the same family include ZSSC4151CE6R (same function, different reel packaging) and ZSSC4151CE4R (different QFN-24 package). Cross-family replacements require verifying pin compatibility and software register mapping.
