5 / 12 page MLX902xx Name of Sensor Rev Y.X 22/Aug/98 Page 5 MLX90711 Position/movement Sensing Auto-Shutoff MLX90711 Position/movement Sensing Auto-Shutoff Page 5 Rev 1.0 15/Sep/00 Depending on the position of the sensor the voltage at the TEST1 output will change. The pin TEST1 is also used as digital I/O during the asic production test. Options Following is a summary of the options that can be changed with the metal mask: Pinout Standard package is 8-pin dual inline package or 8- pin sop package. Side Position Shut-Off The design of the cavity in the pcb, on which the ball of the sensor is moving, as well as the design of the protective cover important aspects. When designed properly the function of the Auto Shut-Off module can also be defined when the module is rotated around the axis perpendicular to the normal axis, even when the ball tends to fall off of the pcb. In the application of an iron this can be useful for defining the functionality when the iron is put at his side. Heating Up feature If the heating up feature is present, it inhibits the Auto Shut-Off function for 1 minute and 30 seconds after the start up sequence regardless of the position or the movement of the iron. If the iron is left immobile the asic will activate the relay output after 1 min and 30 sec added to the time TH (or TV or TD depending on the position). If the heating up feature not present, the Auto Shut- Off function is available as soon as the iron is plugged: so the relay contacts will switch off after a time TH if it is left in the ironing position without movement , or after time TV if it is left vertically up, or after time TD if it is left vertically down. Sensor test mode To measure the performance of the sensor in the module, a sensor test mode is implemented. This test mode is activated via the test pin TEST1, which is normally left open. When connecting the pin TEST1 to an external 12V supply (with respect to the asic ground VSS) via a resistor of 220 Kohm the test mode is activated and the output of the on chip integrator is now available at the pin TEST1.
