PYD 1598

low power DigiPyro TM Infrared Sensing Solutions Product Specification PYD 1598 / 7655 Features • Integrated digitization • Motion detection unit with Interrupt function • Low-power consumption of only 3 µA at 1.8 V. • High responsivity ceramic pyroelectric elements • Dual detector with 2 × 1 mm2 elements • 130◦ field-of-view • TO-5 metal housing for high EMI immunity Low Power Dual Element Large Field-of-View Pyro The PYD 1598 is a serial opposed format, two elements detector based on pyroceramic. The signal is converted to a digital value using Sigma-Delta and DSP techniques. A configurable motion detection unit is implemented. Once motion was detected, an interrupt will be send to the host system. Putting the host system to sleep an overall ultra low power consumption will be achieved. All data is accessible by the host system to enable advanced signal analysis with your own detection criteria. Excelitas digital solutions provide excellent EMI immunity. • Optimal for fast designs Applications • Long distance motion detection (with lens) • Energy saving applications • Intrusion alarms • Horizontal mounting applications • Battery operation • Gesture direction recognition • Touchless switch Issued: 20/03/2018 / Revised: 27/09/2022 Contents 1 Physical Characteristics 1.1 Pyro-Electric Elements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.2 Optical Properties . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.3 Filter Properties . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 Electrical Characteristics 2.1 Absolute Maximum Ratings 2.2 Electrical Data . . . . . . . 2.3 Interface Overview . . . . 2.4 Motion Detection Unit . . 2.5 Configuration Register . . 2.6 Serial In Interface . . . . . 2.7 Direct Link Interface . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 5 6 7 8 8 9 10 11 11 13 13 3 Handling, Operation and Precautions 16 3.1 Handling . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 3.2 Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 4 Quality and Statements 17 5 Packaging 18 PYD 1598 / 7655 Physical Characteristics Table 1: Summary of physical characteristics.

It features a dual element configuration in a serial opposed format. Its typical application is long distance, wall mounted, motion detection . Figure 2: Test set up for the measurement of responsivity and match. 1 2 3 4 6 5 DSP Display Figure 3: Masking of elements to test the electrical parameters. Responsivity A Responsivity B Match Noise Cover Plate The typical set-up for the measurement of responsivity and match is illustrated in figure 2. The black body (BB) radiator (1) is set to 373 K (100 ◦C). The signal is modulated by a rotating chopper (2). An aperture (3) is used to adjust the radiation flux. The cover plate (4) is masking the elements as shown in figure 3. The sensor (5) is interfaced to a signal processing chain (6). To measure noise, a bandpass filter in the range of 0.4 Hz to 10 Hz is applied. Responsivity (R ) and match are measured at a modulation frequency of 1 Hz. The match is defined by Match R × 100 (1) Noise is measured shut from infra-red energy. The measurement is performed after a settling time of 10 min at an ambient temperature of 25 ◦C ± 3 ◦C. Noise is monitored for the duration of 600 s . 5 Excelitas Technologies GmbH & Co.

FOV The horizontal field of view (FOV) as drawn to figure 4 is given as the geometrically unobstructed light path to both elements. The FOV of 130◦ is given for the optical light acceptance with the full so-called common mode suppression. The optical distance as it is given in figure 1 represents the effective focal plane for the application specific optics. The optical distance is shorter than the geometrical due to refraction of light in the filter. 6 Excelitas Technologies GmbH & Co.
