THE SOLE PROPERTY OF SIA MIPEX. ANY REPRODUCTION WITHOUT THE WRITTEN PERMISSION OF SIA MIPEX IS PROHIBITED.
5.3. Electrical conditions
•
During first 0.01 seconds after power up, sensor consumes up to 55 mA, and
then during 0.1 second average current consumption up to 14 mA (see Fig. 1).
After that sensor switches to the normal current consumption mode.
•
During operation, MIPEX-02 has pulsed current consumption. Pulse repetition
period is 80 ± 20% ms (depends on ambient temperature).
•
During operation, maximum surge current is 17 mA for 20 microseconds (see
Fig. 2). Average current consumption is not more than 330 µA when UART is
active (see Fig. 3). For power consumption of sensor connected via barrier see
Fig. 4 and Fig. 5.
Sensor power supply with rated output range DC voltage (U
0
) of +3.0…+5.0 V.
Sensor UART transceiver communication properties are:
•
High logic level for transmitting line TxD is in range of +2.4…+2.7 V;
•
High logic level for receiving line RxD is in range of +2.4…+3.4 V;
•
Low logic level is in range of 0…+0.8 V;
•
Maximum output current of UART is not more than 25 mA.
