About Sensor Signal Conditioners
Most analog signals require some form of preparation before they can be digitized. Sensor signal conditioning is the manipulation of a sensor signal in a way that prepares it for the next stage of processing. Renesas' sensor signal conditioner ICs typically interface with two main sensor types: resistive bridges and differential capacitors. For each sensor type, further specialization allows selecting the optimal balance between price and performance for the required operating voltage and temperature range, gain, resolution, input/output format, and qualification level. Renesas' SSC ICs offer digital compensation of sensor offset, sensitivity, temperature drift, and nonlinearity in wide operational temperature ranges.
Advanced multi-market sensing platform ICs

Renesas Sensor Signal Conditioner ICs are all-in-one, energy-efficient products that are easy to use and are supported by advanced software and expert technical support staff with extensive sensor system design experience. A distinct advantage of our correction algorithms is that they are cali-brated and programmed in an efficient “single-pass” operation that lowers costs by reducing test time and loading of production test equipment without sacrificing precision. Renesas Sensor Signal Conditioner ICs also lower total system costs by simplifying sensor design with our excellent support tools, reducing external components, minimizing board space, and providing a faster migration to production.

ZSSC3154 Automotive Sensor Signal Conditioner with Dual analog output
-
The ZSSC3154 is an integrated circuit for highly accurate amplification and sensor-specific correction of a bridge sensor signal. Up to two temperature sensors can also be read in parallel. The circuitry provides different configurations of the analog outputs to show two measurement results simultaneously.

An internal calibration microcontroller in addition with an on-chip EEPROM performs the digital compensation of the sensor offset, the sensitivity, the temperature drift, and the nonlinearity. The one-pass digital end-of-line calibration plus the integrated broken chip-detection supports automatic and highly efficient mass production.

ZSPM2000: True Digital PWM Controller with Integrated MOSFET Driver
-
The ZSPM2000 is a configurable true-digital single-phase PWM controller for high-current, non-isolated DC/DC supplies. The ZSPM2000 includes a high-speed MOSFET driver for a synchronous step-down converter in a single-rail and single-phase configuration. The ZSPM2000 integrates a digital control loop, optimized for maximum flexibility and stability, as well as load step and steady-state performance. In addition, a rich set of protection and monitoring functions is provided. On-chip, non-volatile memory (NVM) and an I²C interface facilitate configuration.Renesas PC-based Pink Power Designer™ graphical user interface (GUI) provides a user-friendly and easy-to-use interface to the device for communication and configuration. It can guide the user through the design of the digital compensator and offers intuitive configuration methods for additional features, such as protection and sequencing.

Analog DC-DC Regulator Family
Step-down (Buck) Regulators
-
Renesas energy-efficient, synchronous step-down regulators for non-isolated applications provide up to 95% efficiency. The step-down regulators feature integrated driver and power FETs, capable of leveraging a wide input voltage range and supporting up to 12A of output current.
About Step-down Switching Regulators
A step-down, or buck, switching regulator takes an input voltage and efficiently converts it into a regulated lower voltage. Devices typically come with fixed or adjustable output voltages. A good buck regulator will provide high-efficiency and excellent transient response under all load conditions. Buck regulators will often provide special features to ensure protection of the IC during fault conditions, such as under-voltage lockout, thermal shutdown, soft-start, currently limiting, and short-circuit protection.
