NCS36000DG

Sensor And Detector Interfaces Overview

The NCS36000DG is a fully integrated mixed-signal CMOS Passive Infrared (PIR) detector controller manufactured by onsemi. It operates within an analog power supply range of 3.0 V to 5.75 V and supports an ambient temperature range from -40°C to +85°C. The device features two low-noise differential amplifiers, an internal LDO regulator providing a 2.7 V reference, and a window comparator with trip levels at approximately 1.7 V and 2.5 V. It utilizes an external RC oscillator for clock frequency control and includes digital signal processing for single or dual pulse detection. The component is housed in a 14-pin SOIC package.

Sensor And Detector Interfaces Procurement Notes

Verify current availability status before design integration. The datasheet revision history indicates that this device has been discontinued as of November 7, 2025. New designs should consult onsemi representatives for alternative solutions or updated product information. Confirm package markings and ordering suffixes match specific project requirements.

Sensor And Detector Interfaces Selection Notes

Select this component for low-cost PIR control applications requiring integrated signal conditioning. Ensure external components for the bandpass filter and oscillator are chosen to meet specific sensitivity and frequency requirements. Verify that the 10 mA output drive current is sufficient for the connected LED or load. Consider the discontinuation status when planning long-term production lifecycles.

Sensor And Detector Interfaces Part Context

The NCS36000 series is designed specifically for passive infrared sensing applications. It combines analog front-end processing with digital decision-making to reduce system complexity. The DG suffix denotes the SOIC-14 package variant. This device simplifies PIR sensor interfaces by integrating amplification, filtering, and comparison functions into a single CMOS chip.

Sensor And Detector Interfaces Replacement Considerations

The datasheet explicitly states the device is discontinued and not recommended for new designs. Contact onsemi sales representatives for information on current replacement parts or compatible alternatives suitable for PIR detection applications.
