Description

The E910.92 integrated circuit combines all required functions for a single chip Passive Infra Red (PIR) motion detector. A relay and a LED output are provided for interfacing to an occupancy detect or alarm system.

 

Due to the adjustable threshold and TRUE-ROLL time window, the E910.92 IC can be adapted to the requirements of the application. Hereby an optimized detection accuracy is reached.One or two PIR sensors can be connected directly to the PIR inputs. The pull-down resistors and DC decoupling circuitry are integrated on chip. Internally, the PIR sensor signal is converted to a 15 bit digital value.

The parameters for sensitivity, pulse count and timing are set by means of connecting the corresponding inputs to VDD, VSS or leaving them open. The E910.92 voltage level on the temperature compensation input is converted to a digital value with 4 bit resolution. All signal processing is performed digitally.
