For the 1μA type please note that the average current consumption is 1μA in sleep mode and 1.9μA in standby mode. Please also refer to the timing chart. Note 2) Please select an output resistors (pull-down concept) in accordance with Vout so that the output current is lower than or equal to 100μA. If the output current is more than 100μA, this may cause false alarms. Note 3) The sensor temperature has to be constant for the time specified. 【Explanation of modes】 1)Sleep mode: When the output is OFF. The electrical current consumption is around 1μA. 2) Standby mode: After the sensor's output has reached ON status, the sensor switches to standby mode. The electrical current consumption gets close to 1.9μA . When the sensor's output returns to its OFF value after the "hold time" has expired, the sensor switches again to sleep mode. 3) Mask mode: Time during which the output is forced to OFF status after the end of the standby mode. (No detection is possible during this period.) 【Explanation of the timing】 t1 (Twu): Circuit stability time: about 25 sec (typ.) While the circuitry is stabilizing after the power is turned on, the sensor output is not fixed in the ON or OFF state. This is true regardless of whether or not the sensor has detected anything. t2: Standby hold time: about 2.6 sec (typ.) after the last detection of a signal. (※1) t3: Mask time: about 1.3 sec (typ.) During this stage, even if the sensor detects something, the output will not switch to ON.(※2) 【Explanation of the timing】 Twu: Circuit stability time: about 25 sec (typ.) for 2μA type, max. 10 sec for 6μA type. While the circuitry is stabilizing after the power is turned on, the sensor output is not fixed in the ON or OFF state. This is true regardless of whether or not the sensor has detected anything. |
