MC145012DW Description

Short technical summary and product information.

The NXP Semiconductors MC145012DW is an advanced photoelectric smoke detector integrated circuit designed for use in smoke detection systems. It features sophisticated analog and digital circuitry, enabling detection of smoke particles by sensing scattered light. The IC is suitable for applications requiring compliance with UL217 and UL268 specifications.

 

Key electrical characteristics include an operating voltage range of 6.0 V to 12 V and a low average supply current of 8 µA, making it ideal for battery-powered devices. The operating temperature range is from -10°C to 60°C. The MC145012DW includes an I/O pin that allows interconnection of up to 40 units for common signaling, and it supports audible emergency evacuation signals compliant with NFPA 72, ANSI S3.41, and ISO 8201.

 

This component is housed in a 16-SOIC package and is designed for surface mounting. It incorporates electrostatic discharge (ESD) and latch-up protection circuitry on all pins. The IC is Pb-Free, indicating a commitment to environmental standards. Its design facilitates direct interface to IR detectors (photodiodes) and includes on-chip push-pull drivers for an external piezoelectric transducer to sound a pulsating alarm.

 

The MC145012DW is built with 2000 FETs, 12 NPNs, 16 resistors, and 10 capacitors, showcasing its complexity and integration. It is designed to operate in conjunction with an infrared photoelectric chamber for smoke detection.
