Title
IR sensor with signal processing IC
Applications
Indoor Equipment such as Home Information Terminals, Smart Locks, IoT Cameras, and Home Appliances
AK9754

Description

Asahi Kasei Microdevices Corporation, (AKM), has developed a short-range infrared sensor IC, the AK9754, with a built-in Human Approach Detection algorithm.The AK9754 consumes less power because of the built-in algorithm compared to existing systems that need external signal processing.It is suitable for battery-powered applications
The AK9754 integrates AKM’s original InSb quantum IR sensor element, an analog front end circuit for converting the current output of the element to voltage, a dedicated thermometer for measuring the element temperature, a 16-bit A/D converter, (ADC), an I2C interface, and an interrupt output pin.

Features

● Built-in Human Approach Detection Algorithm

Conventional infrared sensor ICs implemented the human presence detection algorithm in an external microcomputer for processing the infrared sensor IC output. Since the AK9754 has the Human Approach Detection algorithm built-in, it performs well by only setting some basic IC settings.


● Low Power Consumption

By using the built-in algorithm and interrupt signal, the AK9754 help achieves long system operation when powered via battery such as keeping the external microcomputer asleep. In addition, output data rates and detection modes can be selected. Current consumption of the device is appropriately adjusted according to the mode selected. (Typ. 5μA at 10Hz Output with Low Noise Mode OFF)


● World Smallest Class, Ultra-compact and Thin Surface Mounting Package

The AK9754 does not need a lens to work up to 1m detection distances.
It is housed in a very compact and thin package, 8-pin SON, (2.2 x 2.2 x t0.6 mm), helping for flexible designs of information terminal devices.
