NCS36000DRG

Sensor And Detector Interfaces Overview

The NCS36000DRG is a fully integrated mixed-signal CMOS Passive Infrared (PIR) detector controller designed for low-cost controlling applications. It operates within a supply voltage range of 3.0 V to 5.75 V and supports an ambient temperature range of -40°C to 85°C. The device integrates two low-noise differential amplifiers, a window comparator, and a digital control circuit. An internal Low Dropout (LDO) regulator provides a nominal 2.7 V reference to drive the sensor. The system utilizes an external RC network connected to the OSC pin to set the clock frequency, typically around 62.5 Hz with standard component values.

Sensor And Detector Interfaces Feature Summary

• Integrates dual-stage differential amplifiers configured as a bandpass filter to condition PIR sensor signals.
• Features an internal LDO regulator providing stable voltage references for the sensor and analog blocks.
• Includes a window comparator that triggers based on high and low trip thresholds relative to internal references.
• Supports single or dual pulse detection modes selectable via the MODE pin.

Sensor And Detector Interfaces Applications

• Automatic lighting systems for residential and commercial environments
• Automation of doors triggered by motion
• Motion-triggered events such as animal photography

Sensor And Detector Interfaces Procurement Notes

Verify current availability status before design finalization. The datasheet revision history indicates this device has been discontinued as of November 2025. New designs should consult onsemi representatives for alternative solutions or updated product recommendations. Confirm package type and marking details match specific project requirements.

Sensor And Detector Interfaces Selection Notes

Select this component for cost-sensitive PIR sensing applications requiring integrated signal conditioning. Ensure the application environment stays within the specified -40°C to 85°C operating range. Designers must provide external components for the oscillator frequency setting and bandpass filter configuration. Verify power supply stability between 3.0 V and 5.75 V to maintain correct comparator thresholds.
