Atlantik Elektronik presents new ultra-low power infrared sensor IC AK9754AE from AKM

World´s smallest class ultra-low power infrared sensor with Human Approach detection algorithm

Planegg, September 24th, 2018

Atlantik Elektronik, provider of innovative sensor solutions, presents the AK9754AE from Asahi Kasei Microdevices. The AK9754 is equipped with a built-in Human Approach Detection algorithm. The infrared sensor consumes less power because of the built-in algorithm compared to existing systems that need external signal processing. This new technology enables us to change our daily life at home to a more convenient, secure, safe, and energy saving environment with sensors. The new AK9754AE is particularly suitable for battery powered applications such as IoT applications, intelligence home appliance, lighting systems, household equipment, smart locks, door phone, home information devices, IoT cameras, home and office devices as well as home automation.
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.

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. 

The new ultra-low power infrared sensor IC AK9754AE from Asahi Kasei Microdevices is available now at Atlantik Elektronik.
